+/**
+ * @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>

+         *
+         * The stylePatterns is a list whose elements have the form
+         * [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
+         *
+         * Style is a style constant like PR_PLAIN, or can be a string of the
+         * form 'lang-FOO', where FOO is a language extension describing the
+         * language of the portion of the token in $1 after pattern executes.
+         * E.g., if style is 'lang-lisp', and group 1 contains the text
+         * '(hello (world))', then that portion of the token will be passed to the
+         * registered lisp handler for formatting.
+         * The text before and after group 1 will be restyled using this decorator
+         * so decorators should take care that this doesn't result in infinite
+         * recursion.  For example, the HTML lexer rule for SCRIPT elements looks
+         * something like ['lang-js', /<[s]cript>(.+?)<\/script>/].  This may match
+         * '<script>foo()<\/script>', which would cause the current decorator to
+         * be called with '<script>' which would not match the same rule since
+         * group 1 must not be empty, so it would be instead styled as PR_TAG by
+         * the generic tag rule.  The handler registered for the 'js' extension would
+         * then be called with 'foo()', and finally, the current decorator would
+         * be called with '<\/script>' which would not match the original rule and
+         * so the generic tag rule would identify it as a tag.
+         *
+         * Pattern must only match prefixes, and if it matches a prefix, then that
+         * match is considered a token with the same style.
+         *
+         * Context is applied to the last non-whitespace, non-comment token
+         * recognized.
+         *
+         * Shortcut is an optional string of characters, any of which, if the first
+         * character, gurantee that this pattern and only this pattern matches.
+         *
