Textmate-bundles is a project mainly written in ..., it's free.
All my textmate bundles as submodules from git
To install all the bundles:
cd ~/Library/Application Support/TextMate
git clone https://github.com/rafaelgaspar/textmate-bundles.git Bundles
cd Bundles
git submodule init && git submodule update
osascript -e 'tell app "TextMate" to reload bundles'
