vim does this from the command line.  this converts a directory full of ruby
files to syntax highlighted html:

   for f in *.rb;do vim -f +"syn on" +"run! syntax/2html.vim" +"wq" +"q" $f;done

it would be trivial to write a ruby app that scanned to the 'indent' class,
extracted all the next before the matching/closing pre, wrote a tmp file,
converted it to html, and munged the html file in place with marked up ruby
code.  let me know if you want me to do it and provide me with a sample html
file unless you think a file save-as from the site will do.

the thing with vim is that it will determine the automatically from either the
file extension or the shebang line - no special css needed.

cheers.
