" 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
