Overview

To install, put this in ~/Library/Application\ Support/Avian/Bundles. TextMate should auto-recognize it and let you select either theme from View → Theme.

You can also use symlinks. For example, I have this repository cloned to ~/Repositories/Stoneship Themes/, with a symlink like so:

ln -s ~/Repositories/Stoneship\ Themes/Stoneship\ Themes.tmbundle ~/Library/Application\ Support/Avian/Bundles
