+/**
+ * @fileoverview
+ * some functions for browser-side pretty printing of code contained in html.
+ *
+ *
+ * For a fairly comprehensive set of languages see the
+ * README
+ * 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.
+ *
+ * Usage:
+ * - include this source file in an html page via
+ * {@code }
+ *
- define style rules. See the example page for examples.
+ *
- mark the {@code
} and {@code } tags in your source with
+ * {@code class=prettyprint.}
+ * You can also use the (html deprecated) {@code } 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, but if you wish, you can add
+ * another class to the {@code } or {@code } element to specify the
+ * language, as in {@code }. 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.
+ *
+ * Change log:
+ * cbeust, 2006/08/22
+ *
+ * Java annotations (start with "@") are now captured as literals ("lit")
+ *
+ * @requires console
+ * @overrides window
