We now have syntax highlighting for a host of languages through Google Prettify. Regrettably, the default set:
lang-bsh lang-c lang-cpp lang-cs lang-csh lang-css lang-hs lang-html lang-java lang-js lang-lisp lang-lua lang-ml lang-perl lang-php lang-proto lang-py lang-rb lang-scala lang-sh lang-sql lang-vb lang-xml
VHDL already has a plugin for Google Prettify. If this is enabled, we'll be better able to serve this portion of our community.
