自己安裝了 snipMate，啟動vim後出現以下錯誤：
Warning in snipMate.vim: Snippet c) is already defined. See :h multi_snip for help on snippets with multiple matches.
Warning in snipMate.vim: Snippet date is already defined. See :h multi_snip for help on snippets with multiple matches.
Press ENTER or type command to continue
[root@localhost ~]# vim hello.c

錯誤原因：
我在/usr/share/vim/vim72和~/.vim分別解壓了 snipMate.zip一次，造成了檔案重複。
解決辦法：
將/usr/share/vim/vim72中snipMate相關的檔案去除即可。
總結一下snipMate的安裝辦法：
1.到http://www.vim.org/scripts/script.php?script_id=2540下載snipMate.zip
2.將snipMate.zip複製到~/.vim,用“unzip snipMate.zip”解壓。如果沒有~/.vim目錄,自己建立。
3.修改~/.vimrc，增加這麼一行：
filetype plugin on
4.啟動Vim開啟一個C檔案，輸入"int main<tab>"看看會發生什麼。
