This is not an addon. It is a Textmate bundle to add extra support for WoW.
What is Textmate?
Textmate is a powerful but simple editor on Macs. It can be found on www.macromates.com
What about Windows?
While I've not tested the bundle under E Editor, it should be compatible from what I know. Check out www.e-texteditor.com for more info.
Requirements
You should go and grab the Lua bundle for this to work properly. It can be found at: http://svn.textmate.org/trunk/Bundles/Lua.tmbundle/ or through the GetBundle bundle. That always amuses me.
