To install this bundle, paste the following into the terminal:

mkdir -p ~/"Library/Application Support/TextMate/Bundles/"
cd ~/"Library/Application Support/TextMate/Bundles/"
git clone git://github.com/kevinweil/pig.tmbundle "Pig.tmbundle"
osascript -e 'tell app "TextMate" to reload bundles'

If you are using Textmate 2:

mkdir -p ~/"Library/Application Support/Avian/Bundles"
cd ~/"Library/Application Support/Avian/Bundles"
if [ -d Pig.tmbundle ]; then rm -rf Pig.tmbundle; fi
git clone git://github.com/kevinweil/pig.tmbundle "Pig.tmbundle"

Enjoy, and please help me improve it! Kevin
