+/* Unobtrustive Code Highlighter By Dan Webb 11/2005
+ Version: 0.4
+
+ Usage:
+ Add a script tag for this script and any stylesets you need to use
+ to the page in question, add correct class names to CODE elements,
+ define CSS styles for elements. That's it!
+
+ Known to work on:
+ IE 5.5+ PC
+ Firefox/Mozilla PC/Mac
+ Opera 7.23 + PC
+ Safari 2
+
+ Known to degrade gracefully on:
+ IE5.0 PC
+
+ Note: IE5.0 fails due to the use of lookahead in some stylesets. To avoid script errors
+ in older browsers use expressions that use lookahead in string format when defining stylesets.
+
+ This script is inspired by star-light by entirely cunning Dean Edwards
+ http://dean.edwards.name/star-light/.
