| /* 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/. | ||
