  /**
   * @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>

   *   Java annotations (start with "@") are now captured as literals ("lit")

      * '(hello (world))', then that portion of the token will be passed to the

      * '<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.
