This is a mirror of version 6.1.1(2014/04/21) of c.vim, from http://www.vim.org/scripts/script.php?script_id=213
The mirror you are using may be https://github.com/vim-scripts/c.vim but it's not the latest version
It seens that the offical github won't update as vim.org update. Thus, this repo is for vundle(or neobundle) to install the latest version of c.vim
Bundle "Lee-W/c.vim.git"
open vi and enter :BundleInstall or NeoBundleInstall in normal mode
