Granted that I just wrote this in the past couple days and that it’s my first time using xslt…

I created an XSL Transformation file for TextMate snippets.
https://github.com/srbs/textmate-to-sublime-converter

Also included is the start of an ant script for converting TextMate bundles into sublime packages.
Eventually the ant script will be translated to bash & possibly batch so stay tuned.
