" File: snipMate.vim
" Author: Michael Sanders
" Version: 0.84
" Description: snipMate.vim implements some of TextMate's snippets features in
" Vim. A snippet is a piece of often-typed text that you can
" insert into your document using a trigger word followed by a "<tab>".
"
" For more help see snipMate.txt; you can do this by using:
" :helptags ~/.vim/doc
" :h snipMate.txt
