+ * 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:

    + *
  1. include this source file in an html page via + * {@code } + *
  2. define style rules. See the example page for examples. + *
  3. 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.
+ * </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.

+    * 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.
