+/**
+ * @fileoverview
+ * some functions for browser-side pretty printing of code contained in html.
+ *
+ * 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 decent subset of Perl, but,
+ * because of commenting conventions, doesn't work on Smalltalk, Lisp-like, or
+ * CAML-like languages.
+ *
+ * If there's a language not mentioned here, then I don't know it, and don't
+ * know whether it works. If it has a C-like, Bash-like, or XML-like syntax
+ * then it should work passably.
+ *
+ * Usage:
+ * 1) include this source file in an html page via
+ * <script type="text/javascript" src="/path/to/prettify.js"></script>
+ * 2) define style rules. See the example page for examples.
+ * 3) mark the <pre> and <code> tags in your source with class=prettyprint.
+ * You can also use the (html deprecated) <xmp> tag, but the pretty printer
+ * needs to do more substantial DOM manipulations to support that, so some
+ * css styles may not be preserved.
+ * 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.
+ *
+ * Change log:
+ * cbeust, 2006/08/22
+ * Java annotations (start with "@") are now captured as literals ("lit")
