" Description : Global Plugin to comment and un-comment different
" source files in both normal and visual <Shift-V> mode
" Last Change : 26th April, 2006
" Created By : Jasmeet Singh Anand <jasanand@hotmail.com>
" Version : 2.2
" Usage : For VIM 6 -
" Stick this file in your ~/.vim/plugin directory or
" in some other 'plugin' directory that is in your runtime path
" For VIM 5 -
" Stick this file somewhere and 'source <path>/comments.vim' it from
" your ~/.vimrc file
" Note : I have provided the following key mappings
" To comment <Ctrl-C> in both normal and visual <Shift-V> range select mode
" To un-comment <Ctrl-X> in both normal and visual <Shift-V> range select mode
" These can be changed based on user's likings or usage
" Contact : For any comments or bug fixes email me at <jasanand@hotmail.com>
