-indentLine
-==========
-
-This plugin is used for displaying thin vertical lines at each indentation leve for code indented with spaces.
-For code indented with tabs, I think there is no need to support it, using :set list lcs=tab:\\|\ (here is a space) can 
-achieve it.
-
-## Requirements
-This plugin takes advantage of newly provided conceal feature in Vim 7.3, so Vim 7.3 with conceal feature is needed.
-
-## Installation
-To install the plugin just copy indentLine.vim into plugin directory.
-
-
-## Setting custom line colors
-For gvim, hi Conceal guifg=(color you like) guibg=NONE
-
-For vim, hi Conceal ctermfg=(color you like) ctermbg=NONE
