fuzzy-finder-textmate (http://github.com/jamis/fuzzyfinder_textmate) is a separate script from FuzzyFinder (http://www.vim.org/scripts/script.php?script_id=1984). FuzzyFinder was the driver. fuzzy-finder-textmate was the adapter that gave command-T to FuzzyFinder.

FuzzyFinder works for things other than just files. It also works on tags, buffers, etc. Also, with updated versions of FuzzyFinder, you no longer need fuzzy-finder-textmate, just that line I posted above.

That said, if all you want is command-T, yeah...FuzzyFinder might be overkill.
