There are many like them, but these are mine.
The Rakefile was stolen from mislav/vimfiles - thanks!
The only real pain is compiling the Ruby extension for Command-T. It needs to
be compiled with the same version of Ruby as vim was compiled with. The
command_t task in the Rakefile should alert you to that though.
Install like so:
git clone git@github.com:tomtaylor/vim-files.git ~/.vim
cd ~/.vim
rake
You'll probably want MacVim or similar installed beforehand.
