+/**
+ * @fileoverview
+ * some functions for browser-side pretty printing of code contained in html.
+ *
+ * <p>
+ * For a fairly comprehensive set of languages see the
+ * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
+ * file that came with this source.  At a minimum, the lexer should work on a
+ * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
+ * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
+ * and a subset of Perl, but, because of commenting conventions, doesn't work on
+ * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
+ * <p>
+ * Usage: <ol>
+ * <li> include this source file in an html page via
+ *   {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
+ * <li> define style rules.  See the example page for examples.
+ * <li> mark the {@code <pre>} and {@code <code>} tags in your source with
+ *    {@code class=prettyprint.}
+ *    You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
+ *    printer needs to do more substantial DOM manipulations to support that, so
+ *    some css styles may not be preserved.
+ * </ol>
+ * That's it.  I wanted to keep the API as simple as possible, so there's no
+ * need to specify which language the code is in, but if you wish, you can add
+ * another class to the {@code <pre>} or {@code <code>} element to specify the
+ * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
+ * starts with "lang-" followed by a file extension, specifies the file type.
+ * See the "lang-*.js" files in this directory for code that implements
+ * per-language file handlers.
+ * <p>
+ * Change log:<br>
+ * cbeust, 2006/08/22
+ * <blockquote>
+ *   Java annotations (start with "@") are now captured as literals ("lit")
+ * </blockquote>
+ * @requires console
+ */
+
+// JSLint declarations
+/*global console, document, navigator, setTimeout, window */

+ * Split {@code prettyPrint} into multiple timeouts so as not to interfere with
+ * UI events.
+ * If set to {@code false}, {@code prettyPrint()} is synchronous.
