I've got a new bundle up on github:
https://github.com/jdonaldson/Parsnip.tmbundle
Parsnip
is a Textmate bundle for creating snippets. It relies on regular
expression syntax in order to flexibly specify tab stops and default
text. It also has the ability to intelligently space and code, or to
easily pass portions of the document through a script (well I think it's
easier than TextMate's base method anyways).
Instructions are on the readme section of the github repo web page.
