hi,
because the homepage of the wiki is a bit down i post this to the list.
i did build 2 bundles and want to share them, probably some find them usefull :) : - mips bundle: syntax-highlighting for mips assemler which you probably need when you write something for spim - graphviz bundle: syntaxhighlighting for dot files, this is maybe usefull when you configured textmate as graphivizs external editor and you want colored keywords.
more information and preview pictures are at http://wiki.macromates.com/textmate/show/TorstenBecker
