-<span id="Agendas-1"></span><h4 class="subsection">5.5.1 Agendas</h4>
-
-<p>To schedule a task to be performed later, an &ldquo;agenda&rdquo; is used.
-There is a default, global agenda that is ready to be used, or
-additional agendas may be created for different purposes. The
-following example prints the text &ldquo;hello&rdquo; when the agenda has
-advanced to time unit 10.
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-symbol">at</span> <span class="syntax-symbol">10</span> <span class="syntax-open">(</span><span class="syntax-symbol">display</span> <span class="syntax-string">"hello\n"</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>Most of the time it is more convenient to schedule tasks relative to
-the current time. This is where <code>after</code> comes in handy:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-symbol">after</span> <span class="syntax-symbol">10</span> <span class="syntax-open">(</span><span class="syntax-symbol">display</span> <span class="syntax-string">"hello\n"</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>Time units in the agenda are in no way connected to real time. It&rsquo;s
-up to the programmer to decide what agenda time means. A simple and
-effective approach is to map each call of the update procedure
-(see <a href="Kernel.html">Kernel</a>) to 1 unit of agenda time, like so:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-open">(</span><span class="syntax-symbol">update</span> <span class="syntax-symbol">dt</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">update-agenda</span> <span class="syntax-symbol">1</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>It is important to call <code>update-agenda</code> periodically, otherwise
-no tasks will ever be run!
-</p>
-<p>In addition to using the global agenda, it is useful to have multiple
-agendas for different purposes. For example, the game world can use a
-different agenda than the user interface, so that pausing the game is
-a simple matter of not updating the world&rsquo;s agenda while continuing to
-update the user interface&rsquo;s agenda. The current agenda is dynamically
-scoped and can be changed using the <code>with-agenda</code> special form:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">game-world-agenda</span> <span class="syntax-open">(</span><span class="syntax-symbol">make-agenda</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-
-<span class="syntax-open">(</span><span class="syntax-symbol">with-agenda</span> <span class="syntax-symbol">game-world-agenda</span>

-</li><li> stream:
-Load chunks of the audio file as needed.

-<p>Play <var>audio</var>. There are many, many knobs to tweak that will
-affect the sound that comes out of the player&rsquo;s speakers.:
-</p>
-<ul>
-<li> <var>pitch</var>:
-Pitch multiplier. The default value of 1.0 means no change in pitch.
-</li><li> <var>volume</var>:
-Volume multiplier. The default value of 1.0 means no change in volume.
-</li><li> <var>min-volume</var>:
-Minimum volume.
-</li><li> <var>max-volume</var>:
-Maximum volume.
-</li><li> <var>max-distance</var>:
-Used with the inverse clamped distance model (the default model) to
-set the distance where there will no longer be any attenuation of the
-source.
-</li><li> <var>reference-distance</var>:
-The distance where the volume for the audio would drop by half (before
-being influenced by the rolloff factor or maximum distance.)
-</li><li> <var>rolloff-factor</var>:
-For slowing down or speeding up the rate of attenuation. The default
-of 1.0 means no attenuation adjustment is made.
-</li><li> <var>cone-outer-volume</var>:
-The volume when outside the oriented cone.
-</li><li> <var>cone-inner-angle</var>:
-Inner angle of the sound cone, in radians. The default value is 0.
-</li><li> <var>cone-outer-angle</var>:
-Outer angle of the sound cone, in radians. The default value is 2pi
-radians, or 360 degrees.
-</li><li> <var>position</var>:
-The source of the sound emitter in 3D space.
-</li><li> <var>velocity</var>:
-The velocity of the sound emitter in 3D space.
-</li><li> <var>direction</var>:
-The direction of the sound emitter in 3D space.
-</li><li> <var>relative?</var>:
-A flag that determines whether the position is in absolute coordinates
-or relative to the listener&rsquo;s location. Absolute coordinates are used
-by default.
-</li></ul>
-
-<p>For games with basic sound needs (that is to say they don&rsquo;t need 3D
-sound modeling), the only things that really matter are <var>volume</var>
-and <var>pitch</var>.

-
-<p>The <code>(chickadee math bezier)</code> module provides an API for
-describing cubic Bezier curves in 2D space. These curves are notably
-used in font description, vector graphics programs, and when it comes
-to games: path building. With Bezier curves, it&rsquo;s somewhat easy to
-create a smooth looking path for an enemy to move along, for example.
-Bezier curves become particularly interesting when they are chained
-together to form a Bezier &ldquo;path&rdquo;, where the end point of one curve
-becomes the starting point of the next.

-<span id="Buffers-1"></span><h4 class="subsection">5.3.12 Buffers</h4>
-
-<p>Alright, let&rsquo;s brush aside all of those pretty high level abstractions
-and discuss what is going on under the hood. The GPU exists as a
-discrete piece of hardware separate from the CPU. In order to make it
-draw things, we must ship lots of data out of our memory space and
-into the GPU. The <code>(chickadee graphics buffer</code>) module provides an
-API for manipulating GPU buffers.
-</p>
-<p>In OpenGL terminology, a chunk of data allocated on the GPU is a
-&ldquo;vertex buffer object&rdquo; or VBO. For example, here is a bytevector
-that could be transformed into a GPU buffer that packs together vertex
-position and texture coordinates:
-</p>

-</span></pre></div>
-
-<p>This data represents a textured 16x16 square centered on the
-origin. To send this data to the GPU, the <code>make-buffer</code> procedure
-is needed:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">buffer</span> <span class="syntax-open">(</span><span class="syntax-symbol">make-buffer</span> <span class="syntax-symbol">data</span> <span class="syntax-keyword">#:stride</span> <span class="syntax-symbol">16</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>The <code>#:stride</code> keyword argument indicates how many bytes make up
-each element of the buffer. In this case, there are 4 floats per
-element: 2 for the vertex, and 2 for the texture coordinate. A 32-bit
-float is 4 bytes in length, so the buffer&rsquo;s stride is 16.
-</p>
-<p>Within a VBO, one or more &ldquo;attributes&rdquo;, as OpenGL calls them, may be
-present. Attributes are subregions within the buffer that have a
-particular data type. In this case, there are two attributes packed
-into the buffer. To define vertex attributes, the
-<code>make-vertex-attribute</code> procedure is needed:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">vertices</span>

-</pre></div>
-
-<p>To render a square, the GPU needs to draw two triangles, which means
-we need 6 vertices in total. However, the above buffer only contains
-data for 4 vertices. This is because there are only 4 unique vertices
-for a square, but 2 of them must be repeated for each triangle. To
-work with deduplicated vertex data, an &ldquo;index buffer&rdquo; must be
-created.
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">index-buffer</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">make-buffer</span> <span class="syntax-open">(</span><span class="syntax-symbol">u32vector</span> <span class="syntax-symbol">0</span> <span class="syntax-symbol">3</span> <span class="syntax-symbol">2</span> <span class="syntax-symbol">0</span> <span class="syntax-symbol">2</span> <span class="syntax-symbol">1</span><span class="syntax-close">)</span>

-</pre></div>
-
-<p>Note the use of the <code>#:target</code> keyword argument. It is required
-because the GPU treats index data in a special way and must be told
-which data is index data.
-</p>
-<p>Now that the vertex attributes have been created, all that&rsquo;s left is
-to bind them all together in a vertex array. Vertex arrays associate
-each vertex attribute with an attribute index on the GPU. The indices
-that are chosen must correspond with the indices that the shader
-(see <a href="Shaders.html">Shaders</a>) expects for each attribute.
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">vertex-array</span>

-</pre></div>
-
-<p>With the vertex array created, the GPU is now fully aware of how to
-interpret the data that it has been given in the original buffer.
-Actually rendering this square is left as an exercise to the reader.
-See the <a href="Shaders.html">Shaders</a> section and the <code>shader-apply</code> procedure in
-<a href="Rendering-Engine.html">Rendering Engine</a> for the remaining pieces of a successful draw
-call. Additionally, consider reading the source code for sprites,
-shapes, or particles to see GPU buffers in action.

-<dd>
-<p>Upload <var>data</var>, a bytevector, to the GPU. By default, the entire

-
-<p>Channels are a tool for communicating amongst different scripts. One
-script can write a value to the channel and another can read from it.
-Reading or writing to a channel suspends that script until there is
-someone on the other end of the line to complete the transaction.

-<span id="Colors-1"></span><h4 class="subsection">5.3.1 Colors</h4>
-
-<p>Merriam-Webster defines color as &ldquo;a phenomenon of light (such as red,
-brown, pink, or gray) or visual perception that enables one to
-differentiate otherwise identical objects.&rdquo; In this essay, I
-will&hellip;
-</p>
-<p>Okay, okay. We all know what colors are. Chickadee provides a data
-type to represent color and some convenient procedures to work with
-them in the <code>(chickadee graphics color)</code> module. Colors are made
-up of four components, or channels: red, green, blue, and alpha
-(transparency.) Each of these values is expressed as a uniform
-floating point value in the range [0, 1]. 0 means that color channel
-is unrepresented in the resulting color, whereas 1 means that color
-channel is at full intensity.
-</p>
-<p>Making a color object is easy, and there&rsquo;s a few ways to do it
-depending on what&rsquo;s most convenient. The first is <code>make-color</code>,
-where you specify each channel exactly as described above. This is
-fully opaque magenta:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-symbol">make-color</span> <span class="syntax-symbol">1.0</span> <span class="syntax-symbol">0.0</span> <span class="syntax-symbol">1.0</span> <span class="syntax-symbol">1.0</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>Many people are used to representing colors as 6 or 8 digit
-hexadecimal numbers, so Chickadee also allows that. Here&rsquo;s magenta,
-again:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-symbol">rgba</span> <span class="syntax-symbol">#xFF00FFFF</span><span class="syntax-close">)</span>
-<span class="syntax-open">(</span><span class="syntax-symbol">rgb</span> <span class="syntax-symbol">#xFF00FF</span><span class="syntax-close">)</span> <span class="syntax-comment">; equivalent to the above

-<p>Easing functions are essential for animation. Each easing function
-provides a different path to go from an initial value to a final
-value. These functions make an excellent companion to the
-<code>tween</code> procedure (see <a href="Tweening.html">Tweening</a>). Experiment with them to
-figure out which function makes an animation look the best.
-</p>
-<p>Pro tip: <code>smoothstep</code> provides nice results most of the time and
-creates smoother animation than using <code>linear</code>.

-<p>A framebuffer is a chunk of memory that the GPU can render things
-onto. By default, the framebuffer that is used for rendering is the
-one belonging to the game window, but custom framebuffers can be used
-as well. A common use-case for custom framebuffers is applying
-post-processing effects: The entire scene is rendered to a
-framebuffer, and then the contents of that framebuffer are applied to
-a post-processing shader and rendered to the game window. The
-post-processing shader could do any number of things: scaling,
-antialiasing, motion blur, etc.

-<span id="Getting-Started-1"></span><h2 class="chapter">2 Getting Started</h2>
-
-<p>One of the simplest programs we can make with Chickadee is rendering
-the text &ldquo;Hello, world&rdquo; on screen. Here&rsquo;s what that looks like:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-open">(</span><span class="syntax-symbol">draw</span> <span class="syntax-symbol">alpha</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">draw-text</span> <span class="syntax-string">"Hello, world!"</span> <span class="syntax-open">(</span><span class="syntax-symbol">vec2</span> <span class="syntax-symbol">64.0</span> <span class="syntax-symbol">240.0</span><span class="syntax-close">)</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>The <code>draw</code> procedure is called frequently to draw the game scene.
-For the sake of simplicity, we will ignore the <code>alpha</code> variable
-in this tutorial.
-</p>
-<p>To run this program, we&rsquo;ll use the <code>chickadee play</code> command:
-</p>
-<div class="example">
-<pre class="example">chickadee play hello.scm
-</pre></div>
-
-<p>This is a good start, but it&rsquo;s boring. Let&rsquo;s make the text move!
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">position</span> <span class="syntax-open">(</span><span class="syntax-symbol">vec2</span> <span class="syntax-symbol">0.0</span> <span class="syntax-symbol">240.0</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-
-<span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-open">(</span><span class="syntax-symbol">draw</span> <span class="syntax-symbol">alpha</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">draw-text</span> <span class="syntax-string">"Hello, world!"</span> <span class="syntax-symbol">position</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-
-<span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-open">(</span><span class="syntax-symbol">update</span> <span class="syntax-symbol">dt</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">set-vec2-x!</span> <span class="syntax-symbol">position</span> <span class="syntax-open">(</span><span class="syntax-symbol">+</span> <span class="syntax-open">(</span><span class="syntax-symbol">vec2-x</span> <span class="syntax-symbol">position</span><span class="syntax-close">)</span> <span class="syntax-open">(</span><span class="syntax-symbol">*</span> <span class="syntax-symbol">100.0</span> <span class="syntax-symbol">dt</span><span class="syntax-close">)</span><span class="syntax-close">)</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>The <code>vec2</code> type is used to store 2D coordinates
-(see <a href="Vectors.html">Vectors</a>.) A variable named <code>position</code> contains the
-position where the text should be rendered. A new hook called
-<code>update</code> has been added to handle the animation. This hook is
-called frequently to update the state of the game. The variable
-<code>dt</code> (short for &ldquo;delta-time&rdquo;) contains the amount of time that
-has passed since the last update, in seconds. Putting it all
-together, this update procedure is incrementing the x coordinate of
-the position by 100 pixels per second.
-</p>
-<p>This is neat, but after a few seconds the text moves off the screen
-completely, never to be seen again. It would be better if the text
-bounced back and forth against the sides of the window.
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">position</span> <span class="syntax-open">(</span><span class="syntax-symbol">vec2</span> <span class="syntax-symbol">0.0</span> <span class="syntax-symbol">240.0</span><span class="syntax-close">)</span><span class="syntax-close">)</span>

- <span class="syntax-open">(</span><span class="syntax-symbol">end</span> <span class="syntax-symbol">536.0</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">duration</span> <span class="syntax-symbol">4.0</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">script</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">while</span> <span class="syntax-symbol">#t</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">tween</span> <span class="syntax-symbol">duration</span> <span class="syntax-symbol">start</span> <span class="syntax-symbol">end</span> <span class="syntax-symbol">update-x</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">tween</span> <span class="syntax-symbol">duration</span> <span class="syntax-symbol">end</span> <span class="syntax-symbol">start</span> <span class="syntax-symbol">update-x</span><span class="syntax-close">)</span><span class="syntax-close">)</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>This final example uses Chickadee&rsquo;s scripting features
-(see <a href="Scripting.html">Scripting</a>) to bounce the text between the edges of the window
-indefinitely using the handy <code>tween</code> procedure. The only thing
-the <code>update</code> procedure needs to do now is advance the clock of
-the &ldquo;agenda&rdquo; (the thing that runs scripts.) The script takes care
-of the rest.
-</p>
-<p>This quick tutorial has hopefully given you a taste of what you can do
-with Chickadee. The rest of this manual gets into all of the details
-that were glossed over, and much more. Try rendering a sprite,
-playing a sound effect, or handling keyboard input. But most
-importantly: Have fun!

-<p>Chickadee aims to make hardware-accelerated graphics rendering as
-simple and efficient as possible by providing high-level APIs that
-interact with the low-level OpenGL API under the hood. Anyone that
-has worked with OpenGL directly knows that it has a steep learning
-curve and a lot of effort is needed to render even a single triangle.
-The Chickadee rendering engine attempts to make it easy to do common
-tasks like rendering a sprite while also providing all of the building
-blocks to implement additional rendering techniques.

-
-<p>The <code>(chickadee data grid)</code> module provides a simple spatial
-partitioning system for axis-aligned bounding boxes
-(see <a href="Rectangles.html">Rectangles</a>) in 2D space. The grid divides the world into
-tiles and keeps track of which rectangles occupy which tiles. When
-there are lots of moving objects in the game world that need collision
-detection, the grid greatly speeds up the process. Instead of
-checking collisions of each object against every other object (an
-O(n^2) operation), the grid quickly narrows down which objects could
-possibly be colliding and only performs collision testing against a
-small set of objects.
-</p>
-<p>In addition to checking for collisions, the grid also handles the
-resolution of collisions. Exactly how each collision is resolved is
-user-defined. A player bumping into a wall may slide against it. An
-enemy colliding with a projectile shot by the player may get pushed
-back in the opposite direction. Two players colliding may not need
-resolution at all and will just pass through each other. The way this
-works is that each time an object (A) is moved within the grid, the
-grid looks for an object (B) that may possibly be colliding with A. A
-user-defined procedure known as a &ldquo;filter&rdquo; is then called with both
-A and B. If the filter returns <code>#f</code>, it means that even if A and
-B are colliding, no collision resolution is needed. In this case the
-grid won&rsquo;t waste time checking if they really do collide because it
-doesn&rsquo;t matter. If A and B are collidable, then the filter returns a
-procedure that implements the resolution technique. The grid will
-then perform a collision test. If A and B are colliding, the resolver
-procedure is called. It&rsquo;s the resolvers job to adjust the objects
-such that they are no longer colliding. The grid module comes with a
-very simple resolution procedure, <code>slide</code>, that adjusts object A
-by the smallest amount so that it no longer overlaps with B. By using
-this filtering technique, a game can resolve collisions between
-different objects in different ways.

-<p>While <code>run-game</code> provides hooks for mouse/keyboard/controller
-input events, it is often necessary to query input devices for their
-current state. For example, it could be desirable to query the state
-of the arrow keys every time the update hook is called to determine
-which direction the player should move that frame.

-<span id="Invoking-chickadee-bundle-1"></span><h3 class="section">3.2 Invoking <code>chickadee bundle</code></h3>
-
-<p>Distributing games is difficult. While Chickadee games are free
-software, it would be far too burdensome on the player to ask them to
-compile a game from source in order to try it out. Many potential
-players will simply not even try. Players expect to be able to
-download a compressed archive, extract it, and play. If there are any
-more steps than that then the chances of the game being played drop
-dramatically. If you can&rsquo;t beat &rsquo;em, join &rsquo;em. The
-<code>chickadee bundle</code> tool creates redistributable binary bundles
-by combining the game code and assets with shared libraries and
-executables from the host operating system.
-</p>
-<p>Bundling is currently only supported on Linux. In the future, it may
-be possible to bundle on MacOS. Patches very much welcome for that.
-</p>
-<p>It should be noted that bundling is a problematic way to distribute
-software. All of the libraries that the bundled application includes
-are separated from the distribution that was so carefully making sure
-that they stay up-to-date with regard to security patches. The
-bundled libraries are frozen in time, vulnerabilities and all.
-Unfortunately, the release model used by the most popular
-distributions, while wonderful for stable, mature software, does not
-fit the needs of game distribution at all. So, we compromise, knowing
-that most games are only played for only a short amount of time before
-being disposed. Perhaps, in time, the Linux world will shift to using
-more robust package management solutions such as
-<a href="https://guix.gnu.org">GNU Guix</a> which support long-term
-maintenance of stable software as well as the &ldquo;fire and forget&rdquo;
-nature of game releases. And maybe a game made with Chickadee will
-become so popular that major distributions decide to package it, but
-let&rsquo;s get back to reality.
-</p>
-<p>To get started with bundling, simply add a <samp>bundle.scm</samp> file to
-the root of the project directory. It could look something like this:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-symbol">'</span><span class="syntax-open">(</span><span class="syntax-open">(</span><span class="syntax-symbol">asset-directories</span> <span class="syntax-symbol">.</span> <span class="syntax-open">(</span><span class="syntax-string">"images"</span> <span class="syntax-string">"models"</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">bundle-name</span> <span class="syntax-symbol">.</span> <span class="syntax-string">"the-legend-of-emacs-1.0"</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">code</span> <span class="syntax-symbol">.</span> <span class="syntax-string">"the-legend-of-emacs.scm"</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">launcher-name</span> <span class="syntax-symbol">.</span> <span class="syntax-string">"the-legend-of-emacs"</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>To create the bundle, simply run <code>chickadee bundle</code>. Upon
-success, the file <samp>the-legend-of-emacs-1.0.tar.gz</samp> would be
-created in the current directory.
-</p>
-<p>To maximize the chances that the bundle will work on someone else&rsquo;s
-computer, it&rsquo;s best to build on the oldest supported Linux
-distribution available. As of this writing, Ubuntu 18.04 LTS is a
-good choice.
-</p>
-<p>In addition to including system libraries and executables,
-<code>chickadee bundle</code> also includes the compiled Guile bytecode
-(the <samp>.go</samp> files) for all modules used by the game. The module
-source files are <em>not</em> included, so it&rsquo;s critical that all of the
-modules used by the game have been compiled.
-</p>
-<p>Available options:
-</p>
-<ul>
-<li> <code>asset-directories</code>
-
-<p>A list of directories that hold static game assets such as images or
-audio. Files in these directories will be copied into the bundle
-archive.
-</p>
-</li><li> <code>binary-directories</code>
-
-<p>A list of directories to search for system binaries, such as
-<code>guile</code>. By default, <samp>/usr/bin</samp> is searched.
-</p>
-</li><li> <code>bundle-name</code>
-
-<p>The name of the bundle archive. By default, the name is
-<code>"chickadee-bundle"</code>.
-</p>
-</li><li> <code>launcher-name</code>
-
-<p>The name of the launcher script. By default, the name is
-<code>"launch-game"</code>.
-</p>
-</li><li> <code>libraries</code>
-
-<p>A list of shared libraries to include in the bundle. By default, all
-of the libraries necessary for running Guile, Guile-SDL2, and
-Chickadee are included. This list is compatible with the names given
-to the libraries on Ubuntu, which may be different than on other
-distributions. In such cases, this list will need to be customized.
-See below for more information on the <code>%default-config</code> variable
-that can be of help.
-</p>
-</li><li> <code>library-directories</code>
-
-<p>A list of directories to search for system shared libraries. By
-default, the list contains common directories used by most
-distributions.
-</p>
-</li><li> <code>method</code>
-
-<p>The method by which the game is launched. Can be either <code>play</code>
-or <code>manual</code>. The default is <code>play</code>, which means that
-<code>chickadee play</code> will be used to launch the game. For games
-that do not use <code>chickadee play</code>, opting to start the game
-loop on their own, the <code>manual</code> method should be used.
-</p>
-</li><li> <code>play-args</code>
-
-<p>A list of command line arguments to pass to <code>chickadee play</code>.
-Only used when the <code>method</code> option is set to <code>play</code>.
-</p>
-</li></ul>
-
-<p>Default configuration options, such as the list of C shared libaries,
-can be found in the <code>%default-config</code> variable. This way they
-can be programatically modified, if necessary.
-</p>
-<dl>
-<dt id="index-_0025default_002dconfig">Variable: <strong>%default-config</strong></dt>
-<dd><p>An association list of default configuration options.
-</p></dd></dl>

-
-<p>The <code>chickadee play</code> command is used to open a window and run
-the Chickadee game contained within a Scheme source file.
-</p>
-<div class="example">
-<pre class="example">chickadee play the-legend-of-emacs.scm
-</pre></div>
-
-<p>In this file, special procedures may be defined to handle various
-events from the game loop:
-</p>
-<ul>
-<li> quit-game
-</li><li> draw
-</li><li> update
-</li><li> key-press
-</li><li> key-release
-</li><li> text-input
-</li><li> mouse-press
-</li><li> mouse-release
-</li><li> mouse-move
-</li><li> mouse-wheel
-</li><li> controller-add
-</li><li> controller-remove
-</li><li> controller-press
-</li><li> controller-release
-</li><li> controller-move
-</li></ul>
-
-<p>See <a href="The-Game-Loop.html">The Game Loop</a> for complete information on all of these
-hooks, such as the arguments that each procedure receives.
-</p>
-<p>In additional to evaluating the specified source file, the directory
-containing that file is added to Guile&rsquo;s load path so that games can
-easily be divided into many different files. Furthermore, that
-directory is entered prior to evaluating the file so that data files
-(images, sounds, etc.) can be loaded relative to the main source file,
-regardless of what the current directory was when <code>chickadee
-play</code> was invoked.
-</p>
-<p>Many aspects of the initial game window and environment can be
-controlled via the following options:
-</p>
-<dl compact="compact">
-<dt><code>--title=<var>title</var></code></dt>
-<dt><code>-t <var>title</var></code></dt>
-<dd>
-<p>Set the window title to <var>title</var>.
-</p>
-</dd>
-<dt><code>--width=<var>width</var></code></dt>
-<dt><code>-w <var>width</var></code></dt>
-<dd>
-<p>Set the window width to <var>width</var> pixels.
-</p>
-</dd>
-<dt><code>--height=<var>height</var></code></dt>
-<dt><code>-h <var>height</var></code></dt>
-<dd>
-<p>Set the window height to <var>height</var> pixels.
-</p>
-</dd>
-<dt><code>--fullscreen</code></dt>
-<dt><code>-f</code></dt>
-<dd>
-<p>Open window in fullscreen mode.
-</p>
-</dd>
-<dt><code>--resizable</code></dt>
-<dt><code>-r</code></dt>
-<dd>
-<p>Make window resizable.
-</p>
-</dd>
-<dt><code>--update-hz=<var>n</var></code></dt>
-<dt><code>-u <var>n</var></code></dt>
-<dd>
-<p>Update the game <var>n</var> times per second.
-</p>
-</dd>
-<dt><code>--clear-color=<var>color</var></code></dt>
-<dt><code>-c <var>color</var></code></dt>
-<dd>
-<p>Set the screen clear color to <var>color</var>, a hex code in the format
-<code>#RRGGBB</code>. For example, to set the clear color to black, pass
-<code>--clear-color=#000000</code>.
-</p>
-</dd>
-<dt><code>--repl</code></dt>
-<dd>
-<p>Launch a REPL in the terminal. This will allow the game environment
-to be debugged and modified without having to stop and restart the
-game after each change.
-</p>
-</dd>
-<dt><code>--repl-server[=<var>port</var>]</code></dt>
-<dd>
-<p>Launch a REPL server on port <var>port</var>, or 37146 by default.
-</p>
-<p><code>telnet localhost 37146</code> (or whatever port number was given)
-will do the trick, but using the <a href="https://www.nongnu.org/geiser/">Geiser</a> extension for Emacs is by far the best way to develop at the
-REPL with Guile. Use <code>M-x connect-to-guile</code> to connect to the
-REPL server.
-</p>
-</dd>
-<dt><code>--language=<var>language</var></code></dt>
-<dd>
-<p>Process the input program using <var>language</var>, the identifier of a
-language within Guile&rsquo;s language tower. By default, unsurprisingly,
-Scheme is used.
-</p>
-<p>For example, to use the neat
-<a href="https://www.draketo.de/software/wisp">Wisp</a> language as an
-alternative to Scheme&rsquo;s parenthetical syntax, pass
-<code>--language=wisp</code>. Wisp is not included with Guile and must be
-installed separately.
-</p>
-</dd>
-<dt><code>-x <var>extension</var></code></dt>
-<dd>
-<p>Add <var>extension</var> to the list of file extensions that Guile will
-load.
-</p>
-<p>For example, Wisp files canonically use the <samp>.w</samp> extension.
-Here&rsquo;s what a &ldquo;hello, world&rdquo; Chickadee program looks like in Wisp:
-</p>
-<div class="example">
-<pre class="example">define : draw alpha
- draw-text "Hello, world!" : vec2 260.0 240.0
-</pre></div>
-
-<p>Assuming the above code is saved to a <samp>hello.w</samp> file,
-<code>chickadee play</code> be invoked as follows:
-</p>
-<div class="example">
-<pre class="example">chickadee play --language=wisp -x .w hello.w
-</pre></div>
-

-<p>The <code>(chickadee graphics light)</code> module provides a data type for
-dynamic lights that can be used to light 3D objects (such as
-<a href="Models.html">Models</a> or <a href="Meshes.html">Meshes</a>.)
-</p>
-<p>There are 3 types of dynamic lights:
-</p>
-<ul>
-<li> point light:
-Emits light in all directions from a specific point in space, like a
-light bulb.
-</li><li> directional light:
-Emits light of a constant intensity in a direction, like sunlight.
-</li><li> spot light:
-Emits a cone of light in a direction, like a flashlight.

-<span id="Live-Coding-1"></span><h2 class="chapter">4 Live Coding</h2>
-
-<p>One of the biggest appeals of any Lisp dialect is the ability to use
-the &ldquo;read-eval-print loop&rdquo; (REPL for short) to build programs
-iteratively and interactively while the program is running. However,
-programs that run in an event loop and respond to user input (such as
-a game using the Chickadee library!) require special care for this
-workflow to be pleasant.
-</p>
-<p>If you are using the <code>chickadee play</code> command to run your
-game, then the <code>--repl</code> or <code>--repl-server</code> arguments are all
-you need to get a live coding environment running.
-</p>
-<p>If, however, you are using <code>run-game</code> to start the game loop then
-it&rsquo;s still fairly easy to hook up a special kind of REPL by yourself.
-</p>
-<p>First, create a cooperative REPL server (It&rsquo;s important to use Guile&rsquo;s
-cooperative REPL server instead of the standard REPL server in
-<code>(system repl server)</code> to avoid thread synchronization issues).
-Then, in the game loop&rsquo;s update procedure, call
-<code>poll-coop-repl-server</code> and pass the REPL object. Here is a
-template to follow:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-symbol">use-modules</span> <span class="syntax-open">(</span><span class="syntax-symbol">chickadee</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">system</span> <span class="syntax-symbol">repl</span> <span class="syntax-symbol">coop-server</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-
-<span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">repl</span> <span class="syntax-open">(</span><span class="syntax-symbol">spawn-coop-repl-server</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-
-<span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-open">(</span><span class="syntax-symbol">update</span> <span class="syntax-symbol">dt</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">poll-coop-repl-server</span> <span class="syntax-symbol">repl</span><span class="syntax-close">)</span>
- <span class="syntax-symbol">...</span><span class="syntax-close">)</span>
-
-<span class="syntax-open">(</span><span class="syntax-symbol">run-game</span> <span class="syntax-keyword">#:update</span> <span class="syntax-symbol">update</span> <span class="syntax-symbol">...</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>To use the REPL, connect to it via port 37146. Telnet will do the
-trick, but using the <a href="https://www.nongnu.org/geiser/">Geiser</a>
-extension for Emacs is by far the best way to develop at the REPL with
-Guile. Use <code>M-x connect-to-guile</code> to connect to the REPL server.

-
-<p>The <code>(chickadee math matrix)</code> module provides an interface for
-working with the most common type of matrices in game development: 4x4
-transformation matrices.
-</p>
-<p><em>Another Note About Performance</em>
-</p>
-<p>Much like the vector API, the matrix API is commonly used in
-performance critical code paths. In order to reduce the amount of
-garbage generated and improve matrix multiplication performance, there
-are many procedures that perform in-place modifications of matrix
-objects.

-
-<p>The <code>(chickadee graphics mesh)</code> modules provides procedures for
-programmatically creating 3D objects (to load 3D models from a file on
-disk, see <a href="#Meshes">Meshes</a>.)
-</p>
-<span id="Materials"></span><h4 class="subsubsection">5.3.11.1 Materials</h4>
-
-<p>Before we talk about meshes themselves, let&rsquo;s discuss &ldquo;materials.&rdquo;
-Materials control the appearance of 3D objects. Whether an object
-appears like a rough rock, a smooth and shiny metal, etc. depends on
-the material that is applied to it. Different types of materials use
-different lighting models. Chickadee supports two lighting models:
-The classic Blinn-Phong model and a more modern physically based
-rendering (PBR) model.
-</p>
-<p>All materials share some common data:
-</p>

-
-<p>Effects like smoke, fire, sparks, etc. are often achieved by animating
-lots of little, short-lived sprites known as &ldquo;particles&rdquo;. In fact,
-all of these effects, and more, can be accomplished by turning a few
-configuration knobs in a &ldquo;particle system&rdquo;. A particle system takes
-care of managing the many miniscule moving morsels so the developer
-can quickly produce an effect and move on with their life. The
-<code>(chickadee graphics particles)</code> module provides an API for
-manipulating particle systems.
-</p>
-<p>Below is an example of a very simple particle system that utilizes
-nearly all of the default configuration settings:

-</pre></div>
-
-<p>In order to put particles into a particle system, a particle
-&ldquo;emitter&rdquo; is needed. Emitters know where to spawn new particles,
-how many of them to spawn, and for how long they should do it.
-</p>
-<p>Below is an example of an emitter that spawns 16 particles per frame
-at the coordinates <code>(320, 240)</code>:

-<p>Return a new particle system that may contain up to <var>capacity</var>
-particles. Achieving the desired particle effect involves tweaking
-the following keyword arguments as needed:
-</p>
-<p>- <var>blend-mode</var>: Pixel blending mode. Alpha blending is used by
-default. (see <a href="Render-Settings.html">Render Settings</a> for more about blend modes).
-</p>
-<p>- <var>start-color</var>: The tint color of the particle at the beginning of its
-life. White by default.
-</p>
-<p>- <var>end-color</var>: The tint color of the particle at the end of of its
-life. Completely transparent by default for a fade-out effect. The
-color in the middle of a particle&rsquo;s life will be an interpolation of
-<var>start-color</var> and <var>end-color</var>.

-texture. Default is 1.
-</p>
-<p>- <var>animation-columns</var>: How many animation frame columns there are
-in the texture. Default is 1.
-</p>
-<p>- <var>width</var>: The width of each particle. By default, the width of

-<p>- <var>height</var>: The height of each particle. By default, the height
-of an animation frame (in pixels) is used.
-</p>
-<p>- <var>speed-range</var>: A 2D vector containing the min and max particle
-speed. Each particle will have a speed chosen at random from this
-range. By default, speed ranges from 0.1 to 1.0.
-</p>
-<p>- <var>acceleration-range</var>: A 2D vector containing the min and max
-particle acceleration. Each particle will have an acceleration chosen
-at random from this range. By default, acceleration ranges from 0.0
-to 0.1.
-</p>
-<p>- <var>direction-range</var>: A 2D vector containing the min and max
-particle direction as an angle in radians. Each particle will have a
-direction chosen at random from this range. By default, the range
-covers all possible angles.
-</p>
-<p>- <var>lifetime</var>: How long each particle lives, measured in
-updates. 30 by default.
-</p>
-<p>- <var>sort</var>: <code>youngest</code> if youngest particle should be drawn
-last or <code>oldest</code> for the reverse. By default, no sorting is
-applied at all.

-
-<p>Most game worlds have maps. Often, these games have a need to move
-non-player characters around in an unscripted fashion. For example,
-in a real-time strategy game, the player may command one of their
-units to attack something in the enemy base. To do so, the unit must
-calculate the shortest route to get there. It wouldn&rsquo;t be a very fun
-game if units didn&rsquo;t know how to transport themselves efficiently.
-This is where path finding algorithms come in handy. The
-<code>(chickadee data path-finding)</code> module provides a generic
-implementation of the popular A* path finding algorithm. Just add a
-map implementation!
-</p>
-<p>The example below defines a very simple town map and finds the
-quickest way to get from the town common to the school.

-<p>In this case, the <code>a*</code> procedure will return the list
-<code>(town-common town-hall school)</code>, which is indeed the shortest
-route. (The other possible route is <code>(town-common library cafe
-school)</code>.)
-</p>
-<p>The <code>a*</code> procedure does not know anything about about any kind of
-map and therefore must be told how to look up neighboring nodes, which
-is what the <code>neighbors</code> procedure in the example does. To
-simulate different types of terrain, a cost procedure is used. In
-this example, it is just as easy to move between any two nodes because
-<code>cost</code> always returns 1. In a real game, perhaps moving from
-from a field to a rocky hill would cost a lot more than moving from
-one field to another. Finally, a heuristic is used to calculate an
-approximate distance between two nodes on the map. In this simple
-association list based graph it is tough to calculate a distance
-between nodes, so the <code>distance</code> procedure isn&rsquo;t helpful and
-always returns 1. In a real game with a tile-based map, for example,
-the heuristic could be a quick Manhattan distance calculation based on
-the coordinates of the two map tiles. Choose an appropriate heuristic
-for optimal path finding!

-
-<p>The <code>(chickadee data quadtree)</code> module provides a 2D spatial
-partitioning implementation known as a &ldquo;quadtree&rdquo;. A quadtree
-recursively subdivides the world into rectangular quadrants. This
-data structure is very useful for handling broad-phase collision
-detection because it can quickly determine the objects that may
-possibly be colliding with another, resulting in fewer narrow-phase
-collision tests that are typically much more expensive.

-<p>In game development, the quaternion is most often used to represent
-rotations. Why not use a matrix for that, you may ask. Unlike
-matrices, quaternions can be interpolated (animated) and produce a
-meaningful result. When interpolating two quaternions, there is a
-smooth transition from one rotation to another, whereas interpolating
-two matrices would yield garbage.

-
-<p>The <code>(chickadee math rect)</code> module provides an API for
-manipulating axis-aligned bounding boxes (AABBs). AABBs are often
-used for collision detection in games. Common use-cases are defining
-&ldquo;hitboxes&rdquo; in platformers or using them for the &ldquo;broad phase&rdquo; of a
-collision detection algorithm that uses a more complex (and thus
-slower) method of determining the actual collisions.
-</p>
-<p>Like some of the other math modules, there exists a collection of
-functions that do in-place modification of rectangles for use in
-performance critical code paths.

-
-<p>Rendering a scene often involves drawing layers of objects that
-overlap each other. Blending determines how two overlapping pixels
-are combined in the final image that is rendered to the screen. The
-<code>(chickadee graphics blend)</code> module provides a data type for
-blending modes.
-</p>
-<p>Chickadee provides the following blend modes:
-</p>
-<dl>
-<dt id="index-blend_003aalpha">Variable: <strong>blend:alpha</strong></dt>

-<p>The <code>(chickadee graphics engine)</code> module provides a Scheme
-abstraction to the state of the GPU driver. When the Chickadee game
-loop launches, it takes care to initialize the engine. All draw calls
-and state changes happen within the context of this engine.
-</p>
-<p>Performing a custom draw call could look something like this:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-symbol">with-graphics-state</span> <span class="syntax-open">(</span><span class="syntax-open">(</span><span class="syntax-symbol">g:blend-mode</span> <span class="syntax-symbol">blend:alpha</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">g:texture-0</span> <span class="syntax-symbol">my-texture</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">shader-apply</span> <span class="syntax-symbol">my-shader</span> <span class="syntax-keyword">#:foo</span> <span class="syntax-symbol">1</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<span id="Render-States"></span><h4 class="subsubsection">5.3.17.1 Render States</h4>
-
-<p>Render states represent individual state values on the GPU. For
-example, the current shader. As a naming convention, Chickadee
-prefixes variables containing render states with <code>g:</code>. Render
-states can be manipulated using the <code>with-graphics-state</code> macro.
-</p>
-<dl>
-<dt id="index-with_002dgraphics_002dstate">Syntax: <strong>with-graphics-state</strong> <em>((name value) &hellip;) body &hellip;</em></dt>
-<dd><p>Evaluate <var>body</var> with render states defined by <var>name</var> changed
-to <var>value</var>. The render states are restored to their previous
-values afterwards.
-</p></dd></dl>
-
-<p>One additional piece of state that the rendering engine has, that is
-not part of the GPU state, is the current projection matrix:
-</p>
-<dl>
-<dt id="index-current_002dprojection">Procedure: <strong>current-projection</strong></dt>
-<dd><p>Return the currently bound projection matrix (see <a href="Matrices.html">Matrices</a>).
-</p></dd></dl>
-
-<dl>
-<dt id="index-with_002dprojection">Syntax: <strong>with-projection</strong> <em>projection body &hellip;</em></dt>
-<dd><p>Evaluate <var>body</var> with the current projection matrix bound to
-<var>projection</var> (see <a href="Matrices.html">Matrices</a>).
-</p></dd></dl>
-
-<span id="Rendering"></span><h4 class="subsubsection">5.3.17.2 Rendering</h4>
-
-<p>Chickadee likens a GPU draw call to a Scheme procedure call. A shader
-(see <a href="Shaders.html">Shaders</a>) is like a procedure for the GPU to apply. Shaders
-are passed arguments: The positional arguments are vertex array
-attributes (see <a href="Buffers.html">Buffers</a>) and the keyword arguments correspond to
-the shader&rsquo;s uniform variables. Scheme uses <code>apply</code> to call a
-procedure, so Chickadee uses <code>shader-apply</code> to call a shader.
-</p>
-<dl>
-<dt id="index-shader_002dapply">Syntax: <strong>shader-apply</strong> <em>shader vertex-array [#:uniform-key uniform-value &hellip;]</em></dt>
-<dt id="index-shader_002dapply_002a">Syntax: <strong>shader-apply*</strong> <em>shader vertex-array count [#:uniform-key uniform-value &hellip;]</em></dt>
-<dd>
-<p>Render <var>vertex-array</var> using <var>shader</var> with the uniform values
-specified in the following keyword arguments.
-</p>
-<p>While <code>shader-apply</code> will draw every vertex in <var>vertex-array</var>,
-<code>shader-apply*</code> will only draw <var>count</var> vertices.
-</p></dd></dl>
-
-<dl>
-<dt id="index-shader_002dapply_002finstanced">Syntax: <strong>shader-apply/instanced</strong> <em>shader vertex-array n [#:uniform-key uniform-value &hellip;]</em></dt>
-<dt id="index-shader_002dapply_002finstanced-1">Syntax: <strong>shader-apply/instanced</strong> <em>shader vertex-array count n [#:uniform-key uniform-value &hellip;]</em></dt>
-<dd>
-<p>Render <var>vertex-array</var> <var>n</var> times using <var>shader</var> with the
-uniform values specified in the following keyword arguments.
-</p>
-<p>Instanced rendering is very beneficial for rendering the same object
-many times with only small differences for each one. For example, the
-particle effects described in <a href="Particles.html">Particles</a> use instanced rendering.
-</p>
-<p>While <code>shader-apply/instanced</code> will draw every vertex in
-<var>vertex-array</var>, <code>shader-apply*</code> will only draw <var>count</var>
-vertices.

-<p>Game logic is a web of asynchronous events that are carefully
-coordinated to bring the game world to life. In order to make an
-enemy follow and attack the player, or move an NPC back and forth in
-front of the item shop, or do both at the same time, a scripting
-system is a necessity. Chickadee comes with an asynchronous
-programming system in the <code>(chickadee scripting)</code> module.
-Lightweight, cooperative threads known as &ldquo;scripts&rdquo; allow the
-programmer to write asynchronous code as if it were synchronous, and
-allow many such &ldquo;threads&rdquo; to run concurrently.
-</p>
-<p>But before we dig deeper into scripts, let&rsquo;s discuss the simple act
-of scheduling tasks.

-
-<p>Now that we can schedule tasks, let&rsquo;s take things to the next level.
-It sure would be great if we could make procedures that described a
-series of actions that happened over time, especially if we could do
-so without contorting our code into a nest of callback procedures.
-This is where scripts come in. With scripts we can write code in a
-linear way, in a manner that appears to be synchronous, but with the
-ability to suspend periodically in order to let other scripts have a
-turn and prevent blocking the game loop. Building on top of the
-scheduling that agendas provide, here is a script that models a child
-trying to get their mother&rsquo;s attention:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-symbol">script</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">while</span> <span class="syntax-symbol">#t</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">display</span> <span class="syntax-string">"mom!"</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">newline</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">sleep</span> <span class="syntax-symbol">60</span><span class="syntax-close">)</span><span class="syntax-close">)</span><span class="syntax-close">)</span> <span class="syntax-comment">; where 60 = 1 second of real time
-</span></pre></div>
-
-<p>This code runs in an endless loop, but the <code>sleep</code> procedure
-suspends the script and schedules it to be run later by the agenda.
-So, after each iteration of the loop, control is returned back to the
-game loop and the program is not stuck spinning in a loop that will
-never exit. Pretty neat, eh?
-</p>
-<p>Scripts can suspend to any capable handler, not just the agenda.
-The <code>yield</code> procedure will suspend the current script and pass
-its &ldquo;continuation&rdquo; to a handler procedure. This handler procedure
-could do anything. Perhaps the handler stashes the continuation
-somewhere where it will be resumed when the user presses a specific
-key on the keyboard, or maybe it will be resumed when the player picks
-up an item off of the dungeon floor; the sky is the limit.
-</p>
-<p>Sometimes it is necessary to abruptly terminate a script after it has
-been started. For example, when an enemy is defeated their AI routine
-needs to be shut down. When a script is spawned, a handle to that
-script is returned that can be used to cancel it when desired.
-</p>

-
-<p>Shaders are programs that the GPU can evaluate that allow the
-programmer to completely customized the final output of a GPU draw
-call. The <code>(chickadee graphics shader)</code> module provides an API for
-building custom shaders.
-</p>
-<p>Shaders are written in the OpenGL Shading Language, or GLSL for short.
-Chickadee aspires to provide a domain specific language for writing
-shaders in Scheme, but we are not there yet.
-</p>
-<p>Shader programs consist of two components: A vertex shader and a
-fragment shader. A vertex shader receives vertex data (position
-coordinates, texture coordinates, normals, etc.) and transforms them
-as desired, whereas a fragment shader controls the color of each
-pixel.
-</p>
-<p>Sample vertex shader:
-</p>
-<div class="example">
-<pre class="verbatim">#version 130
-
-in vec2 position;
-in vec2 tex;
-out vec2 fragTex;
-uniform mat4 mvp;
-
-void main(void) {
- fragTex = tex;
- gl_Position = mvp * vec4(position.xy, 0.0, 1.0);
-}
-</pre></div>
-
-<p>Sample fragment shader:
-</p>
-<div class="example">
-<pre class="verbatim">#version 130
-
-in vec2 fragTex;
-uniform sampler2D colorTexture;
-
-void main (void) {
- gl_FragColor = texture2D(colorTexture, fragTex);
-}
-</pre></div>
-
-<p>This manual will not cover GLSL features and syntax as there is lots
-of information already available about this topic.
-</p>
-<p>One way to think about rendering with shaders, and the metaphor
-Chickadee uses, is to think about it as a function call: The shader is
-a function, and it is applied to some &ldquo;attributes&rdquo; (positional
-arguments), and some &ldquo;uniforms&rdquo; (keyword arguments).
-</p>

-<p>See <a href="Rendering-Engine.html">Rendering Engine</a> for more details about the <code>shader-apply</code>

-</p>
-<p>Shaders are incredibly powerful tools, and there&rsquo;s more information
-about them than we could ever fit into this manual, so we highly
-recommend searching the web for more information and examples. What
-we can say, though, is how to use our API:

-
-<span id="User_002dDefined-Shader-Types"></span><h4 class="subsubsection">5.3.13.3 User-Defined Shader Types</h4>
-
-<p>The shader examples in this manual thus far have only shown uniforms
-defined using primitive types. However, GLSL shaders support
-user-defined compound structs, such as this one:
-</p>
-<div class="example">
-<pre class="verbatim">struct Light {
- bool enabled;
- int type;
- vec3 position;
- vec3 direction;
- vec4 color;
- float intensity;
- float cutOff;
-};
-
-uniform Light light;
-</pre></div>
-
-<p>While <code>light</code> is declared as a single uniform in the shader code,
-OpenGL translates this into <em>seven</em> uniforms in this case: One
-uniform each member of the <code>Light</code> struct. This poses a problem
-for sending Scheme data to the GPU. How can compound Scheme data
-translate into compound uniform data on the GPU? The answer is with
-shader types. Shader types are a special kind of Guile struct that
-provide a one-to-one mapping between a Scheme data structure and a
-shader struct.
-</p>
-<p>Some example code will explain this concept best. Here is the Scheme
-equivalent of the <code>Light</code> struct:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define-shader-type</span> <span class="syntax-symbol">&lt;light&gt;</span>
- <span class="syntax-symbol">make-light</span>
- <span class="syntax-symbol">light?</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">bool</span> <span class="syntax-symbol">enabled</span> <span class="syntax-symbol">light-enabled?</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">int</span> <span class="syntax-symbol">type</span> <span class="syntax-symbol">light-type</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">float-vec3</span> <span class="syntax-symbol">position</span> <span class="syntax-symbol">light-position</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">float-vec3</span> <span class="syntax-symbol">direction</span> <span class="syntax-symbol">light-direction</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">float-vec4</span> <span class="syntax-symbol">color</span> <span class="syntax-symbol">light-color</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">float</span> <span class="syntax-symbol">intensity</span> <span class="syntax-symbol">light-intensity</span><span class="syntax-close">)</span>
- <span class="syntax-open">(</span><span class="syntax-symbol">float</span> <span class="syntax-symbol">cut-off</span> <span class="syntax-symbol">light-cut-off</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p>The macro <code>define-shader-type</code> closely resembles the familiar
-<code>define-record-type</code> from SRFI-9, but with one notable
-difference: Each struct field contains type information. The type
-must be one of several primitive types (documented below) or another
-shader type in the case of a nested structure.
-</p>
-<p>It is important to note that the names of the shader type fields
-<em>must</em> match the names of the struct members in the GLSL code,
-otherwise Chickadee will be unable to perform the proper translation.
-</p>
-<p>As of this writing, this interface is new and experimental. It
-remains to be seen if this model is robust enough for all use-cases.

-<p>While the <code>audio-play</code> procedure provides a quick and convenient
-way to play audio, it has some limitations. What if the audio is a
-long piece of music that might need to be paused or stopped later?
-What if the audio should be looped? What if the volume or pitch needs
-to be altered? For manipulating audio in these ways, a &ldquo;source&rdquo; is
-required. Sources can be thought of like a boombox: They sit
-somewhere in the room and play sound. The pause or stop buttons can
-be pressed; it can be moved somewhere else; the volume knob can be
-adjusted; the CD can be changed.
-</p>
-<p>Sources are a great fit for handling background music, among other
-things. For quick, one-off sound effects, <code>audio-play</code> is a
-better fit.

-<span id="Sprites-1"></span><h4 class="subsection">5.3.3 Sprites</h4>
-
-<p>For those who are new to this game, a sprite is a 2D rectangular
-bitmap that is rendered to the screen. For 2D games, sprites are the
-most essential graphical abstraction. They are used for drawing maps,
-players, NPCs, items, particles, text, etc.
-</p>
-<p>In Chickadee, the <code>(chickadee graphics sprite)</code> module provides the
-interface for working with sprites. Bitmaps are stored in textures
-(see <a href="Textures.html">Textures</a>) and can be used to draw sprites via the
-<code>draw-sprite</code> procedure.

-</p>
-<p>Optionally, other transformations may be applied to the sprite.
-<var>rotation</var> specifies the angle to rotate the sprite, in radians.
-<var>scale</var> specifies the scaling factor as a 2D vector. <var>shear</var>

-<span id="Sprite-Batches"></span><h4 class="subsubsection">5.3.3.1 Sprite Batches</h4>
-
-<p>It&rsquo;s not uncommon to need to draw hundreds or thousands of sprites
-each frame. However, GPUs (graphics processing units) are tricky
-beasts that prefer to be sent few, large chunks of data to render
-rather than many, small chunks. Using <code>draw-sprite</code> on its own
-will involve at least one GPU call <em>per sprite</em>. This is fine
-for rendering a few dozen sprites, but will become a serious
-bottleneck when rendering hundreds or thousands of sprites. To deal
-with this, a technique known as &ldquo;sprite batching&rdquo; is used. Instead
-of drawing each sprite immediately, the sprite batch will build up a
-large buffer of sprites to draw and send them to the GPU all at once.
-There is one caveat, however. Batching only works if the sprites
-being drawn share a common texture. A good strategy for reducing the
-number of different textures is to stuff many bitmaps into a single
-image file and create a &ldquo;texture atlas&rdquo; (see <a href="Textures.html">Textures</a>) to access
-the sub-images within.

-<span id="g_t9_002dPatches"></span><h4 class="subsubsection">5.3.3.2 9-Patches</h4>
-
-<p>A 9-patch is a method of rendering a texture so that it can be
-stretched to cover an area of any size without becoming distorted.
-This is achieved by dividing up the sprite into nine regions:
-</p>
-<ul>
-<li> the center, which can be stretched or tiled horizontally and vertically
-</li><li> the four corners, which are never stretched or tiled
-</li><li> the left and right sides, which can be stretched or tiled vertically
-</li><li> the top and bottom sides, which can be stretched or tiled horizontally
-</li></ul>
-
-<p>The most common application of this technique is for graphical user
-interface widgets like buttons and dialog boxes which are often
-dynamically resizable. By using a 9-patch, they can be rendered at
-any size without scaling artifacts. The <code>(chickadee graphics
-9-patch)</code> module provides this functionality.

-
-<p>At the very core of Chickadee there is an event loop. This loop, or
-&ldquo;kernel&rdquo;, is responsible for ensuring that the game is updated at
-the desired interval, handling input devices, rendering the current
-state of the game world, and handling errors if they occur. The
-kernel implements what is known as a &ldquo;fixed timestep&rdquo; game loop,
-meaning that the game simulation will be advanced by a fixed interval
-of time and will never vary from frame to frame, unlike some other
-styles of game loops. The appropriately named <code>run-game</code> and
-<code>abort-game</code> procedures are the entry and exit points to the
-Chickadee game loop.
-</p>
-<p>If you are using <code>chickadee play</code> to launch your game, then
-calling <code>run-game</code> is already taken care of for you.
-</p>

-
-<p>If no error handler is specified, exceptions will simply be re-raised.
-</p>
-</li></ul>
-
-</dd></dl>
-
-<p>To stop the game loop, simply call <code>abort-game</code>.
-</p>
-<dl>
-<dt id="index-abort_002dgame">Procedure: <strong>abort-game</strong></dt>
-<dd><p>Stop the currently running Chickadee game loop.
-</p></dd></dl>
-
-<p>The above explanation of the game loop was partially a lie. It&rsquo;s true
-that there is a game loop at the center of Chickadee, but
-<code>run-game</code> is not it&rsquo;s true entry point. There exists an even
-lower level procedure, <code>run-game*</code>, in the <code>(chickadee
-game-loop)</code> module that <code>run-game</code> uses under the hood.
-</p>
-<p>On its own, <code>run-game*</code> does not do very much at all. In order
-to actually respond to input events, update game state, or render
-output, the developer must provide an engine. <code>run-game</code> is such
-an engine, and it&rsquo;s likely all a developer will need. However, what
-if a developer wanted to use all of the useful Chickadee features to
-make a terminal roguelike game instead? Chickadee doesn&rsquo;t come with a
-terminal rendering engine, but the developer could write one without
-having to write their own core game loop.
-</p>
-<dl>
-<dt id="index-run_002dgame_002a">Procedure: <strong>run-game*</strong> <em>[#:init] [#:update] [#:render] [#:time] [#:error] [#:update-hz 60]</em></dt>
-<dd>
-<p>Start the game loop. This procedure will not return until
-<code>abort-game</code> is called.
-</p>
-<p>The core game loop is generic and requires four additional procedures
-to operate:
-</p>
-<ul>
-<li> <var>init</var>: Called just before game loop is started. Use it to
-perform game initialization.
-</li><li> <var>update</var>: Called <var>update-hz</var> times per second to advance the
-game simulation. This procedure is called with a single argument: The
-amount of time that has passed since the last update, in milliseconds.
-</li><li> <var>render</var>: Called each iteration of the loop to render the game to
-the desired output device. This procedure is called with a single
-argument: A value in the range [0, 1] which represents how much time
-has past since the last game state update relative to the upcoming
-game state update, as a percentage. Because the game state is updated
-independent of rendering, it is often the case that rendering is
-occuring between two updates. If the game is rendered as it was
-during the last update, a strange side-effect will occur that makes
-animation appear rough or &ldquo;choppy&rdquo;. To counter this, the
-<var>alpha</var> value can be used to perfrom a linear interpolation of a
-moving object between its current position and its previous position.
-This odd trick has the pleasing result of making the animation look
-smooth again, but requires keeping track of previous state.
-</li><li> <var>time</var>: Called to get the current time in seconds. This procedure
-is called with no arguments.
-</li><li> <var>error</var>: Called when an error from the <var>update</var> or
-<var>render</var> procedures reaches the game loop. This procedure is
-called with three arguments: The call stack, the error key, and the
-error arguments. If no error handler is provided, the default
-behavior is to simply re-throw the error.
-</li></ul>
-

-
-<p>A tile map is a scene created by composing lots of small sprites,
-called &ldquo;tiles&rdquo;, into a larger image. One program for editing such
-maps is called <a href="http://mapeditor.org">Tiled</a>. Chickadee has native
-support for loading and rendering Tiled maps in the <code>(chickadee
-graphics tile-map)</code> module.

-
-<p>The <code>(chickadee graphics path)</code> module can be used to draw lines,
-curves, circles, rectangles, and more in a scalable, resolution
-independent manner. It is <em>not</em> an SVG compliant renderer, nor
-does it intend to be. However, those familiar with SVG and/or the
-HTML5 Canvas API should find lots of similarities.
-</p>
-<p><em>This API is considered to be experimental and may change
-substantially in future releases of Chickadee. There are many missing
-features.</em>
-</p>
-<p>The first step to rendering vector graphics is to create a
-<em>path</em>: A series of commands that can be thought of as moving a
-pen around a piece of paper. A path can be either open or closed. A
-closed path draws a straight line from the last point in the path to
-the first.

-<dt id="index-path">Procedure: <strong>path</strong> <em>. commands</em></dt>

-
-<p>Unlike Scheme&rsquo;s vector data type, which is a sequence of arbitrary
-Scheme objects, Chickadee&rsquo;s <code>(chickadee math vector)</code> module
-provides vectors in the linear algebra sense: Sequences of numbers
-specialized for particular coordinate spaces. As of now, Chickadee
-provides 2D and 3D vectors, with 4D vector support coming in a future
-release.
-</p>
-<p>Here&rsquo;s a quick example of adding two vectors:
-</p>
-<div class="lisp">
-<pre class="lisp"><span class="syntax-open">(</span><span class="syntax-special">define</span> <span class="syntax-symbol">v</span> <span class="syntax-open">(</span><span class="syntax-symbol">vec2+</span> <span class="syntax-open">(</span><span class="syntax-symbol">vec2</span> <span class="syntax-symbol">1</span> <span class="syntax-symbol">2</span><span class="syntax-close">)</span> <span class="syntax-open">(</span><span class="syntax-symbol">vec2</span> <span class="syntax-symbol">3</span> <span class="syntax-symbol">4</span><span class="syntax-close">)</span><span class="syntax-close">)</span><span class="syntax-close">)</span>
-</pre></div>
-
-<p><em>A Note About Performance</em>
-</p>
-<p>A lot of time has been spent making Chickadee&rsquo;s vector operations
-perform relatively efficiently in critical code paths where excessive
-garbage generation will cause major performance issues. The general
-rule is that procedures ending with <code>!</code> perform an in-place
-modification of one of the arguments in order to avoid allocating a
-new vector. These procedures are also inlined by Guile&rsquo;s compiler in
-order to take advantage of optimizations relating to floating point
-math operations. The downside is that since these are not pure
-functions, they do not compose well and create more verbose code.

-<p>A viewport represents a subset of the screen (or framebuffer). When

-viewport. These aren&rsquo;t often needed, and Chickadee&rsquo;s default viewport
-occupies the entire screen, but there are certain situations where

-<div class="display">
-<pre class="display">Copyright &copy; 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
-<a href="http://fsf.org/">http://fsf.org/</a>
-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-</pre></div>
-
-<ol start="0">
-<li> PREAMBLE
-
-<p>The purpose of this License is to make a manual, textbook, or other
-functional and useful document <em>free</em> in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-</p>
-<p>This License is a kind of &ldquo;copyleft&rdquo;, which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-</p>
-<p>We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-</p>
-</li><li> APPLICABILITY AND DEFINITIONS
-
-<p>This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License. Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein. The &ldquo;Document&rdquo;, below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as &ldquo;you&rdquo;. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-</p>
-<p>A &ldquo;Modified Version&rdquo; of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-</p>
-<p>A &ldquo;Secondary Section&rdquo; is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document&rsquo;s overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject. (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-</p>
-<p>The &ldquo;Invariant Sections&rdquo; are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License. If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant. The Document may contain zero
-Invariant Sections. If the Document does not identify any Invariant
-Sections then there are none.
-</p>
-<p>The &ldquo;Cover Texts&rdquo; are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License. A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-</p>
-<p>A &ldquo;Transparent&rdquo; copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text. A copy that is not &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
-</p>
-<p>Examples of suitable formats for Transparent copies include plain
-ASCII without markup, Texinfo input format, LaTeX input
-format, SGML or XML using a publicly available
-DTD, and standard-conforming simple HTML,
-PostScript or PDF designed for human modification. Examples
-of transparent image formats include PNG, XCF and
-JPG. Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, SGML or
-XML for which the DTD and/or processing tools are
-not generally available, and the machine-generated HTML,
-PostScript or PDF produced by some word processors for
-output purposes only.
-</p>
-<p>The &ldquo;Title Page&rdquo; means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, &ldquo;Title Page&rdquo; means
-the text near the most prominent appearance of the work&rsquo;s title,
-preceding the beginning of the body of the text.
-</p>
-<p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
-of the Document to the public.
-</p>
-<p>A section &ldquo;Entitled XYZ&rdquo; means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language. (Here XYZ stands for a
-specific section name mentioned below, such as &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.) To &ldquo;Preserve the Title&rdquo;
-of such a section when you modify the Document means that it remains a
-section &ldquo;Entitled XYZ&rdquo; according to this definition.
-</p>
-<p>The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document. These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-</p>
-</li><li> VERBATIM COPYING
-
-<p>You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-</p>
-<p>You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-</p>
-</li><li> COPYING IN QUANTITY
-
-<p>If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document&rsquo;s license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-</p>
-<p>If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-</p>
-<p>If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-</p>
-<p>It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-</p>
-</li><li> MODIFICATIONS
-
-<p>You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-</p>
-<ol type="A" start="1">
-<li> Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document). You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-</li><li> List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-</li><li> State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-</li><li> Preserve all the copyright notices of the Document.
-
-</li><li> Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-</li><li> Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-</li><li> Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document&rsquo;s license notice.
-
-</li><li> Include an unaltered copy of this License.
-
-</li><li> Preserve the section Entitled &ldquo;History&rdquo;, Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page. If
-there is no section Entitled &ldquo;History&rdquo; in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-</li><li> Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on. These may be placed in the &ldquo;History&rdquo; section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-</li><li> For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-</li><li> Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles. Section numbers
-or the equivalent are not considered part of the section titles.
-
-</li><li> Delete any section Entitled &ldquo;Endorsements&rdquo;. Such a section
-may not be included in the Modified Version.
-
-</li><li> Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or
-to conflict in title with any Invariant Section.
-
-</li><li> Preserve any Warranty Disclaimers.
-</li></ol>
-
-<p>If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version&rsquo;s license notice.
-These titles must be distinct from any other section titles.
-</p>
-<p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
-nothing but endorsements of your Modified Version by various
-parties&mdash;for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-</p>
-<p>You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity. If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-</p>
-<p>The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-</p>
-</li><li> COMBINING DOCUMENTS
-
-<p>You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-</p>
-<p>The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-</p>
-<p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
-in the various original documents, forming one section Entitled
-&ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
-and any sections Entitled &ldquo;Dedications&rdquo;. You must delete all
-sections Entitled &ldquo;Endorsements.&rdquo;
-</p>
-</li><li> COLLECTIONS OF DOCUMENTS
-
-<p>You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-</p>
-<p>You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-</p>
-</li><li> AGGREGATION WITH INDEPENDENT WORKS
-
-<p>A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an &ldquo;aggregate&rdquo; if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation&rsquo;s users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-</p>
-<p>If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document&rsquo;s Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-</p>
-</li><li> TRANSLATION
-
-<p>Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-</p>
-<p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-</p>
-</li><li> TERMINATION
-
-<p>You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-</p>
-<p>However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-</p>
-<p>Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-</p>
-<p>Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-</p>
-</li><li> FUTURE REVISIONS OF THIS LICENSE
-
-<p>The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns. See
-<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
-</p>
-<p>Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License &ldquo;or any later version&rdquo; applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation. If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy&rsquo;s public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.
-</p>
-</li><li> RELICENSING
-
-<p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works. A
-public wiki that anybody can edit is an example of such a server. A
-&ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-</p>
-<p>&ldquo;CC-BY-SA&rdquo; means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,

-
-<p>To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-</p>
-<div class="example">
-<pre class="example"> Copyright (C) <var>year</var> <var>your name</var>.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.3
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-</pre></div>
-
-<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the &ldquo;with&hellip;Texts.&rdquo; line with this:
-</p>
-<div class="example">
-<pre class="example"> with the Invariant Sections being <var>list their titles</var>, with
- the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
- being <var>list</var>.
-</pre></div>
-
-<p>If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-</p>
-<p>If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

-<p>Guile-SDL2 provides both low-level and high-level Guile Scheme
-bindings to the Simple DirectMedia Layer version 2.0 C library. The
-bindings are written in pure Scheme by using Guile&rsquo;s foreign function
-interface. In addition to the SDL2 core library, bindings are also
-provided for the SDL2_image, SDL2_mixer, and SDL2_ttf add-on
-libraries.
-</p>
-<p>While Guile-SDL2 does provide direct, low-level bindings for the SDL2
-C API, its main feature is exposing high-level interfaces that Scheme
-programmers will find comfortable to use, hiding away the ugly,
-foreign C details. This manual will cover only the high-level API.
-see <a href="API-Reference.html">API Reference</a>
-</p>
-<p>As of this writing, the bindings are useful, but <em>incomplete</em>.
-If you find an SDL2 feature that you cannot use with Guile-SDL2, let
-us know and maybe send a patch! see <a href="Contributing.html">Contributing</a>

-<p>Builders are procedures that return one or more page objects
-(see <a href="Pages.html">Pages</a>) when applied. A builder accepts two arguments: A site
-(see <a href="Sites.html">Sites</a>) and a list of posts (see <a href="Posts.html">Posts</a>).

-<p>Haunt comes with a few convenient builders to help users who want to

-<div class="example">
-<pre class="example">./configure

-
-<p>This will install Haunt to <samp>/usr/local/</samp>. This is not part of

-distribution&rsquo;s package manager (<samp>/usr</samp> is.) You may choose to
-change the prefix to your GNU Guile&rsquo;s location with <code>./configure
---prefix=/usr</code> or add <samp>/usr/local/</samp> to GNU Guile&rsquo;s load path in
-your shell environment like this (replacing 3.0 with your GNU Guile
-version):
-</p>
-<div class="example">
-<pre class="example">export GUILE_LOAD_PATH=&quot;/usr/local/share/guile/site/3.0\

-</div>
-
-<div class="display">
-<pre class="display">Copyright &copy; 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
-<a href="http://fsf.org/">http://fsf.org/</a>
-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-</pre></div>
-
-<ol start="0">
-<li> PREAMBLE
-
-<p>The purpose of this License is to make a manual, textbook, or other
-functional and useful document <em>free</em> in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-</p>
-<p>This License is a kind of &ldquo;copyleft&rdquo;, which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-</p>
-<p>We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-</p>
-</li><li> APPLICABILITY AND DEFINITIONS
-
-<p>This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License. Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein. The &ldquo;Document&rdquo;, below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as &ldquo;you&rdquo;. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-</p>
-<p>A &ldquo;Modified Version&rdquo; of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-</p>
-<p>A &ldquo;Secondary Section&rdquo; is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document&rsquo;s overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject. (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-</p>
-<p>The &ldquo;Invariant Sections&rdquo; are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License. If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant. The Document may contain zero
-Invariant Sections. If the Document does not identify any Invariant
-Sections then there are none.
-</p>
-<p>The &ldquo;Cover Texts&rdquo; are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License. A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-</p>
-<p>A &ldquo;Transparent&rdquo; copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text. A copy that is not &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
-</p>
-<p>Examples of suitable formats for Transparent copies include plain
-ASCII without markup, Texinfo input format, LaTeX input
-format, SGML or XML using a publicly available
-DTD, and standard-conforming simple HTML,
-PostScript or PDF designed for human modification. Examples
-of transparent image formats include PNG, XCF and
-JPG. Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, SGML or
-XML for which the DTD and/or processing tools are
-not generally available, and the machine-generated HTML,
-PostScript or PDF produced by some word processors for
-output purposes only.
-</p>
-<p>The &ldquo;Title Page&rdquo; means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, &ldquo;Title Page&rdquo; means
-the text near the most prominent appearance of the work&rsquo;s title,
-preceding the beginning of the body of the text.
-</p>
-<p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
-of the Document to the public.
-</p>
-<p>A section &ldquo;Entitled XYZ&rdquo; means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language. (Here XYZ stands for a
-specific section name mentioned below, such as &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.) To &ldquo;Preserve the Title&rdquo;
-of such a section when you modify the Document means that it remains a
-section &ldquo;Entitled XYZ&rdquo; according to this definition.
-</p>
-<p>The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document. These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-</p>
-</li><li> VERBATIM COPYING
-
-<p>You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-</p>
-<p>You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-</p>
-</li><li> COPYING IN QUANTITY
-
-<p>If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document&rsquo;s license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-</p>
-<p>If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-</p>
-<p>If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-</p>
-<p>It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-</p>
-</li><li> MODIFICATIONS
-
-<p>You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-</p>
-<ol type="A" start="1">
-<li> Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document). You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-</li><li> List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-</li><li> State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-</li><li> Preserve all the copyright notices of the Document.
-
-</li><li> Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-</li><li> Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-</li><li> Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document&rsquo;s license notice.
-
-</li><li> Include an unaltered copy of this License.
-
-</li><li> Preserve the section Entitled &ldquo;History&rdquo;, Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page. If
-there is no section Entitled &ldquo;History&rdquo; in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-</li><li> Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on. These may be placed in the &ldquo;History&rdquo; section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-</li><li> For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-</li><li> Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles. Section numbers
-or the equivalent are not considered part of the section titles.
-
-</li><li> Delete any section Entitled &ldquo;Endorsements&rdquo;. Such a section
-may not be included in the Modified Version.
-
-</li><li> Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or
-to conflict in title with any Invariant Section.
-
-</li><li> Preserve any Warranty Disclaimers.
-</li></ol>
-
-<p>If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version&rsquo;s license notice.
-These titles must be distinct from any other section titles.
-</p>
-<p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
-nothing but endorsements of your Modified Version by various
-parties&mdash;for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-</p>
-<p>You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity. If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-</p>
-<p>The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-</p>
-</li><li> COMBINING DOCUMENTS
-
-<p>You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-</p>
-<p>The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-</p>
-<p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
-in the various original documents, forming one section Entitled
-&ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
-and any sections Entitled &ldquo;Dedications&rdquo;. You must delete all
-sections Entitled &ldquo;Endorsements.&rdquo;
-</p>
-</li><li> COLLECTIONS OF DOCUMENTS
-
-<p>You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-</p>
-<p>You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-</p>
-</li><li> AGGREGATION WITH INDEPENDENT WORKS
-
-<p>A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an &ldquo;aggregate&rdquo; if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation&rsquo;s users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-</p>
-<p>If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document&rsquo;s Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-</p>
-</li><li> TRANSLATION
-
-<p>Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-</p>
-<p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-</p>
-</li><li> TERMINATION
-
-<p>You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-</p>
-<p>However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-</p>
-<p>Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-</p>
-<p>Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-</p>
-</li><li> FUTURE REVISIONS OF THIS LICENSE
-
-<p>The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns. See
-<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
-</p>
-<p>Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License &ldquo;or any later version&rdquo; applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation. If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy&rsquo;s public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.
-</p>
-</li><li> RELICENSING
-
-<p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works. A
-public wiki that anybody can edit is an example of such a server. A
-&ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-</p>
-<p>&ldquo;CC-BY-SA&rdquo; means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-</p>
-<p>&ldquo;Incorporate&rdquo; means to publish or republish a Document, in whole or
-in part, as part of another Document.
-</p>
-<p>An MMC is &ldquo;eligible for relicensing&rdquo; if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole
-or in part into the MMC, (1) had no cover texts or invariant sections,
-and (2) were thus incorporated prior to November 1, 2008.
-</p>
-<p>The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.
-</p>
-</li></ol>
-
-<span id="ADDENDUM_003a-How-to-use-this-License-for-your-documents"></span><h3 class="heading">ADDENDUM: How to use this License for your documents</h3>
-
-<p>To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-</p>
-<div class="example">
-<pre class="example"> Copyright (C) <var>year</var> <var>your name</var>.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.3
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-</pre></div>
-
-<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the &ldquo;with&hellip;Texts.&rdquo; line with this:
-</p>
-<div class="example">
-<pre class="example"> with the Invariant Sections being <var>list their titles</var>, with
- the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
- being <var>list</var>.
-</pre></div>
-
-<p>If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-</p>
-<p>If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

-
-<p>Haunt is a hackable static site generator written in Guile Scheme. A
-static site generator assists an author with generating the HTML pages
-that they publish on the web. Unlike &ldquo;content management systems&rdquo;
-such as Wordpress or Drupal, static site generators are not dynamic
-web applications (complete with a relational database) that build
-pages on-the-fly. Instead, web pages are built in advance, on the
-author&rsquo;s computer, and copied to a web server when it is time to
-publish changes. The consequence of this design is that the web
-server no longer needs to run a complex, potentially insecure web
-application that connects to a database to retrieve data. Static
-files can be served easily by any generic web server. Since there is
-no web application or database server to deal with, static websites
-are easier to maintain, more secure, and resistant to high web traffic
-(&ldquo;slashdotting.&rdquo;) Furthermore, the entire website is stored in
-plain text, which allows the files to be version-controlled rather
-than kept in a relational database with no concept of history that
-needs to be backed up regularly.
-</p>
-<p>At the time that Haunt was conceived, there existed literally hundreds
-of other static site generators. Why add another one? Haunt
-differentiates itself from most other static site generators in that
-it aspires to the Emacs philosophy of &ldquo;practical software freedom.&rdquo;
-Not only is the source code available under a Free Software license,
-as most static site generators are, it is designed to be easily hacked
-and extended without altering the core source code. Haunt
-purposefully blurs the line between document and program, author and
-programmer, by embracing the notion of data as code. A Haunt-based
-website is not simply data, but a computer program. This design
-strategy encourages authors to automate repetitive tasks and empowers
-them to extend the software with their own ideas.
-</p>
-<p>To make such a system work well, a general-purpose, extensible
-programming language is needed. A traditional configuration file
-format simply will not do. The programming language that we feel is
-best suited to this task is Scheme, a clean and elegant dialect of
-Lisp. We believe that by giving authors the full expressive power of
-Scheme, they will be able to produce better websites and make better
-use of their time than with less programmable systems and less capable
-programming languages. Authors should feel empowered to hack the
-system to make it do what they want rather than what some programmer
-decided they should want. And perhaps most importantly, building
-websites with Haunt should be <em>fun</em>.
-</p>
-<p>Websites written in Haunt are described as purely functional programs
-that accept &ldquo;posts&rdquo;, text documents containing arbitrary metadata,
-as input and transform them into complete HTML pages using Scheme
-procedures. Haunt has no opinion about what markup language authors
-should use to write their posts and will happily work with any format
-for which a &ldquo;reader&rdquo; procedure exists. Likewise, Haunt also has no
-opinion about how authors should structure their sites, but has sane
-defaults. Currently, there exist helpful &ldquo;builder&rdquo; procedures that
-do common tasks such as generating a blog or Atom feed. While the
-built-in features may be enough for some, they surely will not be
-enough for all. Haunt&rsquo;s Scheme API empowers authors to easily tweak
-existing components, write replacements, or add entirely new features
-that do things no else has thought to do yet.
-</p>
-<p>Happy haunting!

-<p>The <code>haunt serve</code> command allows one to quickly view a local
-preview of the generated website before publishing the finished
-product to a remote web server. When <code>haunt serve</code> runs, a
-local HTTP server is spawned. Visit the server using a web browser to
-inspect the results of the build. By default, the web server listens
-on port 8080, so the URL to visit would be
-<a href="http://localhost:8080">http://localhost:8080</a>.
-</p>
-<p>While developing, it is common to rebuild the site frequently to view
-the results of incremental changes. Rather than manually running
-<code>haunt build</code> (<a href="Invoking-haunt-build.html">Invoking haunt build</a>) each time changes
-are made, the <code>--watch</code> flag can be used to automatically rebuild
-the site when a source file changes on disk.

-<span id="Tutorial-1"></span><h2 class="chapter">3 Tutorial</h2>
-
-<p>The goal of this tutorial is to quickly create a barebones blog with
-Haunt in order to demonstrate the basic workflow and key concepts.
-</p>
-<p>First, create a directory for the new site:
-</p>
-<div class="example">
-<pre class="example">mkdir haunt-tutorial
-cd haunt-tutorial
-</pre></div>
-
-<p>Next, create the site configuration file <samp>haunt.scm</samp>. This is
-where all of the code for building the website will go.
-</p>
-<p>Here&rsquo;s what a simple Haunt configuration looks like:
-</p>
-<div class="example">
-<pre class="example">(use-modules (haunt asset)
- (haunt site)
- (haunt builder blog)
- (haunt builder atom)
- (haunt reader skribe))
-
-(site #:title &quot;My First Haunt Site&quot;
- #:domain &quot;example.com&quot;
- #:default-metadata
- '((author . &quot;Eva Luator&quot;)
- (email . &quot;eva@example.com&quot;))
- #:readers (list skribe-reader)
- #:builders (list (blog)
- (atom-feed)
- (atom-feeds-by-tag)))
-</pre></div>
-
-<p>Haunt represents the full configuration of the website using the
-<code>site</code> procedure. Site objects specify things like the site
-title, the default metadata to use for posts, which markup formats are
-supported, and which builders are used to generate web pages.
-</p>
-<p>With the above code saved into the <samp>haunt.scm</samp> file, the next
-step is to create a <samp>posts</samp> directory and populate it with
-articles to publish. Put the text below into a file named
-<samp>posts/hello.skr</samp>:
-</p>
-<div class="example">
-<pre class="example">(post
- :title &quot;Hello, World!&quot;
- :date (make-date* 2015 10 15)
- :tags '(&quot;hello&quot;)
-
- (h1 [Hello, World!])
-
- (p [This is my very first Skribe document!]))
-</pre></div>
-
-<p>This is a
-<a href="http://www.nongnu.org/skribilo/doc/user-3.html#skribe-syntax">Skribe</a> document. Skribe is one of the built-in languages that Haunt
-knows how to work with. It&rsquo;s basically Scheme, but with support for
-writing literal text without quoting it all by enclosing it in square
-brackets. The code above defines a post named &ldquo;Hello, World!&rdquo; with
-a publishing date of 2015-10-15, whose contents are just a single
-heading and a paragraph.
-</p>
-<p>To build the site, run <code>haunt build</code> to compile all of the
-HTML pages. To view the results, run <code>haunt serve</code> and visit
-<a href="http://localhost:8080">http://localhost:8080</a> in a web browser. <code>haunt serve</code>
-is a handy utility that serves the contents of the website using
-Guile&rsquo;s built-in HTTP server. Since the blog builder was specified in
-<samp>haunt.scm</samp>, the default index page is a simple listing of all
-posts, which for now is a single post. Clicking on the post title
-will display a page with only that post&rsquo;s contents.
-</p>
-<p>In addition to the basic blog builder, the <samp>haunt.scm</samp> file
-specifies two additional builders for Atom feeds. The
-<code>atom-feed</code> builder creates a feed of all posts located at
-<a href="http://localhost:8080/feed.xml">http://localhost:8080/feed.xml</a>. The <code>atom-feeds-by-tag</code>
-builder creates one feed for each unique tag specified in the post
-metadata. There&rsquo;s only one tag right now, &ldquo;hello&rdquo;, and its feed is
-located at <a href="http://localhost/feeds/tags/hello.xml">http://localhost/feeds/tags/hello.xml</a>.
-</p>
-<p>Tweaking a post, rebuilding the site, and viewing the results in a web
-browser is the typical Haunt workflow. However, having to run
-<code>haunt build</code> every after each edit is tedious. To address
-this, run <code>haunt serve --watch</code>. The Haunt web server, in
-addition to serving web pages, will now watch for changes to important
-files and automatically rebuild the site when they are edited. This
-streamlines the workflow into an edit, save, view loop.
-</p>
-<p>Now that we&rsquo;ve introduced the basic utilities and concepts, continue
-reading this manual to learn more about Haunt&rsquo;s command-line and
-programming interfaces.

-<p>Agendas are used to schedule procedures to be called at distinct
-points in time. One agenda, stored in the <code>current-agenda</code>
-parameter, is active at any given time. A global agenda is initially
-bound and is sufficient for most needs. When a separate scheduler is
-required (see <a href="REPL.html#REPL">REPL</a> for one such case), the parameter can be
-rebound using <code>parameterize</code> or <code>with-agenda</code> form.

-<p><a href="Coroutines.html#Coroutines">Coroutines</a> become particularly useful for game programming when

-fashion. Sly&rsquo;s coroutines are built on top of Guile&rsquo;s delimited
-continuations, called prompts.
-</p>
-<p>To run a procedure as a coroutine, use the <code>call-with-coroutine</code>
-procedure. Once inside the coroutine prompt, the <code>yield</code>
-procedure can be used to pause the procedure and pass its continuation
-to a callback procedure. The callback may call the continuation at
-its convenience, resuming the original procedure.
-</p>
-<p>Coroutines are particularly useful in conjunction with <a href="Agendas.html#Agendas">Agendas</a>.

-<p>To run an example, invoke Guile with the relevant file, such as:
-<code>guile simple.scm</code>. If successful, a window with a sprite in the
-center will open.
-</p>
-<p>A more complex example can further test your installation and show off

-<div align="center">Version 1.3, 3 November 2008
-</div>
-
-<div class="display">
-<pre class="display">Copyright &copy; 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
-<a href="http://fsf.org/">http://fsf.org/</a>
-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-</pre></div>
-
-<ol>
-<li> PREAMBLE
-
-<p>The purpose of this License is to make a manual, textbook, or other
-functional and useful document <em>free</em> in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-</p>
-<p>This License is a kind of &ldquo;copyleft&rdquo;, which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-</p>
-<p>We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-</p>
-</li><li> APPLICABILITY AND DEFINITIONS
-
-<p>This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License. Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein. The &ldquo;Document&rdquo;, below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as &ldquo;you&rdquo;. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-</p>
-<p>A &ldquo;Modified Version&rdquo; of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-</p>
-<p>A &ldquo;Secondary Section&rdquo; is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document&rsquo;s overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject. (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-</p>
-<p>The &ldquo;Invariant Sections&rdquo; are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License. If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant. The Document may contain zero
-Invariant Sections. If the Document does not identify any Invariant
-Sections then there are none.
-</p>
-<p>The &ldquo;Cover Texts&rdquo; are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License. A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-</p>
-<p>A &ldquo;Transparent&rdquo; copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text. A copy that is not &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
-</p>
-<p>Examples of suitable formats for Transparent copies include plain
-ASCII without markup, Texinfo input format, LaTeX input
-format, SGML or XML using a publicly available
-DTD, and standard-conforming simple HTML,
-PostScript or PDF designed for human modification. Examples
-of transparent image formats include PNG, XCF and
-JPG. Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, SGML or
-XML for which the DTD and/or processing tools are
-not generally available, and the machine-generated HTML,
-PostScript or PDF produced by some word processors for
-output purposes only.
-</p>
-<p>The &ldquo;Title Page&rdquo; means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, &ldquo;Title Page&rdquo; means
-the text near the most prominent appearance of the work&rsquo;s title,
-preceding the beginning of the body of the text.
-</p>
-<p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
-of the Document to the public.
-</p>
-<p>A section &ldquo;Entitled XYZ&rdquo; means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language. (Here XYZ stands for a
-specific section name mentioned below, such as &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.) To &ldquo;Preserve the Title&rdquo;
-of such a section when you modify the Document means that it remains a
-section &ldquo;Entitled XYZ&rdquo; according to this definition.
-</p>
-<p>The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document. These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-</p>
-</li><li> VERBATIM COPYING
-
-<p>You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-</p>
-<p>You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-</p>
-</li><li> COPYING IN QUANTITY
-
-<p>If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document&rsquo;s license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-</p>
-<p>If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-</p>
-<p>If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-</p>
-<p>It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-</p>
-</li><li> MODIFICATIONS
-
-<p>You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-</p>
-<ol>
-<li> Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document). You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-</li><li> List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-</li><li> State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-</li><li> Preserve all the copyright notices of the Document.
-
-</li><li> Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-</li><li> Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-</li><li> Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document&rsquo;s license notice.
-
-</li><li> Include an unaltered copy of this License.
-
-</li><li> Preserve the section Entitled &ldquo;History&rdquo;, Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page. If
-there is no section Entitled &ldquo;History&rdquo; in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-</li><li> Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on. These may be placed in the &ldquo;History&rdquo; section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-</li><li> For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-</li><li> Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles. Section numbers
-or the equivalent are not considered part of the section titles.
-
-</li><li> Delete any section Entitled &ldquo;Endorsements&rdquo;. Such a section
-may not be included in the Modified Version.
-
-</li><li> Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or
-to conflict in title with any Invariant Section.
-
-</li><li> Preserve any Warranty Disclaimers.
-</li></ol>
-
-<p>If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version&rsquo;s license notice.
-These titles must be distinct from any other section titles.
-</p>
-<p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
-nothing but endorsements of your Modified Version by various
-parties&mdash;for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-</p>
-<p>You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity. If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-</p>
-<p>The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-</p>
-</li><li> COMBINING DOCUMENTS
-
-<p>You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-</p>
-<p>The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-</p>
-<p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
-in the various original documents, forming one section Entitled
-&ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
-and any sections Entitled &ldquo;Dedications&rdquo;. You must delete all
-sections Entitled &ldquo;Endorsements.&rdquo;
-</p>
-</li><li> COLLECTIONS OF DOCUMENTS
-
-<p>You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-</p>
-<p>You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-</p>
-</li><li> AGGREGATION WITH INDEPENDENT WORKS
-
-<p>A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an &ldquo;aggregate&rdquo; if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation&rsquo;s users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-</p>
-<p>If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document&rsquo;s Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-</p>
-</li><li> TRANSLATION
-
-<p>Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-</p>
-<p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-</p>
-</li><li> TERMINATION
-
-<p>You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-</p>
-<p>However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-</p>
-<p>Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-</p>
-<p>Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-</p>
-</li><li> FUTURE REVISIONS OF THIS LICENSE
-
-<p>The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns. See
-<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
-</p>
-<p>Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License &ldquo;or any later version&rdquo; applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation. If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy&rsquo;s public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.
-</p>
-</li><li> RELICENSING
-
-<p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works. A
-public wiki that anybody can edit is an example of such a server. A
-&ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-</p>
-<p>&ldquo;CC-BY-SA&rdquo; means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-</p>
-<p>&ldquo;Incorporate&rdquo; means to publish or republish a Document, in whole or
-in part, as part of another Document.
-</p>
-<p>An MMC is &ldquo;eligible for relicensing&rdquo; if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole
-or in part into the MMC, (1) had no cover texts or invariant sections,
-and (2) were thus incorporated prior to November 1, 2008.
-</p>
-<p>The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.

-<a name="ADDENDUM_003a-How-to-use-this-License-for-your-documents"></a>
-<h3 class="heading">ADDENDUM: How to use this License for your documents</h3>
-
-<p>To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-</p>
-<div class="smallexample">
-<pre class="smallexample"> Copyright (C) <var>year</var> <var>your name</var>.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.3
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-</pre></div>
-
-<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the &ldquo;with&hellip;Texts.&rdquo; line with this:
-</p>
-<div class="smallexample">
-<pre class="smallexample"> with the Invariant Sections being <var>list their titles</var>, with
- the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
- being <var>list</var>.
-</pre></div>
-
-<p>If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-</p>
-<p>If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

-<h2 class="chapter">1 Introduction</h2>
-
-<p>Sly is a 2D/3D game engine written in the GNU Guile dialect of the
-Scheme programming language. With the help of Guile, Sly provides all
-of the essential building blocks for making video games, such as:
-window management, input even handling, rendering, linear algebra, and
-powerful scripting capabilities. Sly differentiates itself from
-traditional game engines by providing a dynamic live codinng
-environment and a functional API.
-</p>
-<p>For those unfamiliar with the term, &ldquo;live coding&rdquo; is the practice of
-improvised interactive programming. Sly provides a suitable
-environment for live coding by leveraging Guile&rsquo;s cooperative REPL
-server. When used with a powerful editing tool such as Emacs (with
-the fantastic Geiser extension), programmers may evaluate arbitrary
-code and see the effects of their modifications in real time. This
-tight feedback loop allows for faster prototyping, greater
-productivity, and most importantly, more fun.
-</p>
-<p>Functional reactive programming (FRP) is a technique used to model
-time-varying values with pure functions. A pure function is a
-function whose return value depends solely upon its arguments. They
-also produce no side-effects, such as calling &rsquo;set!&rsquo; on a variable or
-writing to a file on disk. Sly encapsulates time-varying values in
-&ldquo;signals&rdquo;, a high-level data structure for controlling the flow of
-events. Unlike imperative event callbacks, signals can easily be
-composed to form new signals. By modeling game state with pure
-functions and immutable data, a game can be seen as a function of
-time. To play the game is to &ldquo;fold&rdquo; (accumulate a result) over
-time. Constructing a game this way allows for deterministic behavior
-that is easier to reason about and test than the accumulation of
-side-effects seen in traditional game engines. The signal interface
-is also declarative, meaning that the programmer describes <em>what</em>
-the state of the world should be like at any given time, rather than
-<em>how</em> to get there.

-defining rectangular regions, such as the hitbox of a game entity, or
-the viewport of a camera. Because rects are axis-aligned, they
-provide a cheap means to perform simple collision detection.

-<h4 class="subsection">4.3.1 Signals</h4>
-
-<div class="example">
-<pre class="example">(use-modules (sly signal))
-</pre></div>
-
-<p>Game state is a function of time. The player&rsquo;s score, the current
-stage, an enemy&rsquo;s hit points, etc. all change in response to events
-that happen at discrete points in time. Typically, this means that a
-number of callback procedures are registered to respond to events
-which mutate the relevant data structures. However, this approach,
-while simple and effective, comes at the price of readability,
-reproducibility, and expression. Instead of explicitly mutating data
-and entering &ldquo;callback hell&rdquo;, Sly abstracts and formalizes the
-process using a functional reactive programming style.
-</p>
-<p>In Sly, time-varying values are called &ldquo;signals&rdquo;, and they are
-defined in a declarative and functional manner. Rather than
-describing the process of mutation procedurally, one describes the
-relationships between signals instead. The result is a &ldquo;signal
-graph&rdquo;, a directed acyclic graph of event responses.
-</p>
-<div class="example">
-<pre class="example">(define-signal position
- (signal-fold v+ (vector2 320 240)
- (signal-map (lambda (v) (v* v 4))
- (signal-sample 1 key-arrows))))
-</pre></div>
-
-<p>This signal describes a relationship between the arrow keys on the
-keyboard and the position of the player. <code>signal-sample</code> is used
-to trigger a signal update upon every game tick that provides the
-current state of the arrow keys. <code>key-arrows</code> is a 2D vector
-that maps to the current state of the arrow keys, allowing for 8
-directional movement. This vector is then scaled 4x to make the
-player move faster. Finally, the scaled vector is added to the
-previous player position via <code>signal-fold</code>. The player&rsquo;s
-position is at (320, 240) initially. As you can see, there are no
-callbacks and explicit mutation needed, and the position seems to
-magically change with the passage of time.

-<h3 class="section">4.3 Time</h3>
-
-<p>In the context of Sly, time is not the seconds that are passing in the
-real world, but the virtual clock that is ticking within the game
-loop. This manual refers to a &ldquo;tick&rdquo; as the smallest unit of time.
-There are a user-defined amount of ticks in a real world second, but
-by default it is 60.
-</p>
-<p>Sly includes several useful modules for working with time. Coroutines
-are procedures that can be paused and resumed, agendas are procedure
-schedulers, and signals built atop both agendas and coroutines to
-provide a high-level functional reactive programming API.
-</p>
-<p>For most use-cases, the signal module should be used exclusively, but
-the agenda and coroutine modules are useful for building new
-high-level abstractions.

-<p>Transforms are 4x4 transformation matrices. Matrices are the
-fundamental structure for modeling affine transformations such as
-translation, rotation, and scaling. Complex transformations are
-created by composing many simpler ones with the <code>transform*</code>
-procedure.
-</p>
-<p>It&rsquo;s a good idea to use transforms in a functional manner by treating
-them as immutable. This is made easy because almost every procedure
-in this module returns a new transform rather than mutating an
-existing one. However, in some cases it is necessary to use mutable
-transforms via <code>transform*!</code> for performance reasons.

-<p>Not to be confused with Guile&rsquo;s vector data structure, Sly provides
-dedicated data types for 2D, 3D, and 4D vectors in the mathematical
-sense. Vector procedures are polymorphic, and will work with any
-dimensionality that the operation supports. In some cases, such as
-<code>v+</code>, <code>v-</code>, and <code>v*</code>, scalar values may be passed as
-well.
-</p>
-<p>The <code>&lt;vector2&gt;</code>, <code>&lt;vector3&gt;</code>, and <code>&lt;vector4&gt;</code> type
-descriptors have been exposed for use with Guile&rsquo;s <code>(ice-9
-match)</code> pattern matching module.

-
-<p>Sly uses the windowing features of SDL 1.2 under the hood, which
-currently restricts Sly applications to using only a single window.
-SDL2 support will come in a future release.
-</p>
-<p>The window data structure:
-</p>
-<dl>
-<dt><a name="index-make_002dwindow"></a>Scheme Procedure: <strong>make-window</strong> <em>[<var>#:title</var>] [<var>#:resolution</var>] [<var>#:fullscreen?</var>]</em></dt>
-<dd><p>Create a new window object. <code>title</code> is a string to display in
-the window&rsquo;s title bar. <code>resolution</code> is a 2D vector that
-specifies the dimensions of the window in pixels. <code>fullscreen?</code>
-is a boolean that toggles fullscreen mode.
-</p></dd></dl>
-
-<dl>
-<dt><a name="index-window_003f"></a>Scheme Procedure: <strong>window?</strong> <em><var>obj</var></em></dt>
-<dd><p>Return <code>#t</code> if <code>obj</code> is a window.

-
-<dl>
-<dt><a name="index-window_002dtitle"></a>Scheme Procedure: <strong>window-title</strong> <em><var>window</var></em></dt>
-<dd><p>Return the title of <code>window</code>.
-</p></dd></dl>
-
-<dl>
-<dt><a name="index-window_002dresolution"></a>Scheme Procedure: <strong>window-resolution</strong> <em><var>window</var></em></dt>
-<dd><p>Return the resolution of <code>window</code>.
-</p></dd></dl>
-
-<dl>
-<dt><a name="index-window_002dfullscreen_003f"></a>Scheme Procedure: <strong>window-fullscreen?</strong> <em><var>window</var></em></dt>
-<dd><p>Return <code>#t</code> if <code>window</code> is set to fullscreen mode.
-</p></dd></dl>
-
-<p>The following signals hold the state of the current window:
-</p>
-<dl>
-<dt><a name="index-window_002dwidth"></a>Scheme Signal: <strong>window-width</strong></dt>
-<dd><p>The width of the current window.
-</p></dd></dl>
-
-<dl>

-<dd><p>The height of the current window.
-</p></dd></dl>
-
-<dl>
-<dt><a name="index-window_002dsize"></a>Scheme Signal: <strong>window-size</strong></dt>
-<dd><p>The size of the current window as a 2D vector.
-</p></dd></dl>
-
-<p>In addition to signals, the following hooks are triggered upon certain
-changes to window state:
-</p>
-<dl>
-<dt><a name="index-window_002dresize_002dhook"></a>Scheme Variable: <strong>window-resize-hook</strong></dt>
-<dd><p>This hook is run when the current window is resized. Procedures added
-to this hook should accept two arguments: Numbers <code>width</code> and
-<code>height</code>, the new dimensions of the window in pixels.
-</p></dd></dl>
-
-<dl>
-<dt><a name="index-window_002dclose_002dhook"></a>Scheme Variable: <strong>window-close-hook</strong></dt>
-<dd><p>This hook is run when the close button is clicked. Note that this
-event is simply a request from the user to close the window, it does
-not mean that the window has actually been closed. Procedures added
-to this hook should accept no arguments.
-</p></dd></dl>
-
-<p>The following procedures are used to open/close windows:
-</p>
-<dl>
-<dt><a name="index-open_002dwindow"></a>Scheme Procedure: <strong>open-window</strong> <em>[<var>window</var>]</em></dt>
-<dd><p>Open the game window using the settings in <code>window</code>.

-<dl>
-<dt><a name="index-close_002dwindow"></a>Scheme Procedure: <strong>close-window</strong></dt>
-<dd><p>Close the currently open window.
-</p></dd></dl>
-
-<dl>
-<dt><a name="index-with_002dwindow"></a>Scheme Syntax: <strong>with-window</strong> <em><var>window</var> <var>body</var> &hellip;</em></dt>
-<dd><p>Evaluate <code>body</code> in the context of <code>window</code>. <code>window</code>
