+* Things To Do
+
+** DONE Game loop
+   Provide a game loop structure that responds to input events,
+   updates the game state, renders the scene. Use a fixed update
+   timestep and cap the maximum FPS.
+
+** TODO Input
+   Provide hooks to respond to keyboard, mouse, and joystick events.
+   Wrap SDL keycode, mouse button, etc. constants in our own
+   enumeration.
+
+   - [X] Keyboard
+   - [X] Mouse
+   - [X] Window (active, resize, quit)
+   - [ ] Joystick
+
+** DONE Sprites
+   Encapsulates an image and all of its transformations: position,
+   rotation, scale, color, etc.
+
+   - [X] Add support for texture regions
+   - [X] Add support for animations
+   - [X] Use a sprite batch when drawing if one is currently bound
+
+** TODO Sprite batches
+   Efficiently render a large number of sprites. Only change OpenGL
+   context when necessary. For example, don't change texture when
+   rendering several sprites in a row that use the same one.
+
+   - [X] Add basic batching for non-scaled, non-rotated sprites
+   - [X] Add transformation logic for scaling and rotating
+   - [X] Add support for colors
+   - [ ] Add support for different blending modes
+
+** DONE Tilesets
+   Break an image up into many small pieces. Useful for creating maps.
+
+** DONE Animations
+   Create a data type to represent an animated sequence of textures
+   and/or texture regions.
+
+** TODO Tile maps
+   - [ ] Create a generic tilemap module
+   - [ ] Create a loader for Tiled .tmx map files.
+
+** TODO Scene graph
+   A tree structure that is traversed when rendering a game scene.
+   The graph is composed of groups and nodes. Transformations are
+   accumulated as the tree is walked.
+
+** DONE Scripting
+   Provide a way for users to easily script 2D games using coroutines
+   and a scheduler.
+
+** TODO Vectors and matrices
+   Vectors and matrices are needed constantly for games. Provide an
+   easy-to-use module that provides procedures for common
+   vector/matrix math operations
+
+   - [X] Vectors
+   - [ ] Matrices
+
+** TODO Fonts
+   - [ ] Fixed width bitmap font rendering
+   - [ ] Truetype font rendering via freetype
+
+** TODO Sound
+   Provide helpful wrappers around SDL sound procedures?
+
+** TODO A* pathfinding
+   A* is a commonly used pathfinding algorithm for games. Pathfinding
+   is such a common task that it would be nice to provide users with
+   a generic implementation.
+
+** TODO Bounding box collision detection
+   Most games need simple bounding box collision detection. Provide an
+   efficient implementation that uses quad trees.
+
+** TODO Particle systems
+   Provide a highly configurible particle simulation system.
+
+** TODO Asset Management
+   Provide a generic system for loading assets (images, sounds, fonts,
+   etc.) and storing them in a cache. Explore using weak keys so that
+   assets are removed from the cache when they are no longer
+   referenced.
+
+** TODO Actions
+   Provide a library of coroutines that perform commonly used
+   time-based actions such as linear interpolation. It would be nice
+   to have a way to make these easily composable as well.
+
+   - [ ] Linear interpolation (lerp)
+   - [ ] Move to/move by
+
+
+** TODO Combos
+   Provide an Emacs-like way of defining key combinations to that
+   multi-button input is easy for users.
+
+   - [ ] Basic sequences (press A then B)
+   - [ ] Simultaneous key presses (press A and B at the same time)
+   - [ ] Timeouts (combos fail if you don't enter them quick enough)
+
+** TODO 0.1 Release
+   An official 0.1 alpha release with basic, minimal functionality
+   will provide a good place for people other than me to try out
+   guile-2d and perhaps even start to hack on it.
+
+   - [ ] Finish sprite batches
+   - [ ] Basic font rendering
+
+     I don't know of any freetype bindings for Guile, so maybe basic
+     fixed-width bitmap font support will be all that is possible for
+     now.
+
+   - [ ] Resolve issues with FIGL
+
+     Can't have a broken dependency.
+
+   - [ ] Texinfo documentation
+   - [X] Autotools build files
