Syntax coloring PHP examples

While trying to learn DocBook and the other pets that we use to generate the manual, I stumbled across the colorize.php-script that can be found in cvs/peardoc. Why don't we use that script in our manual (well, atleast when building phpweb). It only matches <PRE CLASS="php">, which will be generated when doing <programlisting role="php">, so it won't break other program listings, like ini files and similar. There isn't too hard to generate a similar script to syntax highlight ini, sh and apache configuration files (which I could do if you'd like me too). Just some thoughts. Comments? // Victor
