+<dd><p>Create a new theme named <var>name</var>.
+</p>
+<p>The procedure <var>layout</var> accepts three arguments: a site, a page
+title string, and an SXML tree. Its purpose is to wrap the contents
+of a post with the theme&rsquo;s header/footer and return the complete SXML
+tree for a web page.
+</p>
+<p>The procedure <var>post-template</var> accepts a single argument: a post.
+Its purpose is to return an SXML tree containing the contents of the
+post, applying any desired post-processing operations. The values
+returned from this procedure will be wrapped in the theme&rsquo;s layout.
+</p>
+<p>The procedure <var>collection-template</var> accepts four arguments: a
+site, a title string, a list of posts, and a URL prefix string. Its
+purpose is to return an SXML tree containing the body of the
+collection page. The values returned from this procedure will be
+wrapped in the theme&rsquo;s layout.

+<p>Additionally, this builder creates pages that aggregate previews of

+<dd><p>A procedure that accepts a list of posts as its only argument and
+returns a new list of posts. The filter procedure is used to remove
+and/or sort the posts into the desired form for the collection. For
+example, a filter could sort posts in reverse chronological order or
+select all posts that are written by a particular author.
