+" Section: Documentation {{{1
+"
+" This plugin will highlight tabs and trailing spaces on a line, with the
+" ability to toggle the highlighting on and off. Using highlighting to
+" illuminate these characters is preferrable to using listchars and set list
+" because it allows you to copy from the vim window without getting shrapnel
+" in your buffer.
+"
+" NOTE: "set list" will override SpaceHi's highlighting.
+"
+" Highlighting can be turned on and off with the functions SpaceHi() and
+" NoSpaceHi() respectively. You can also toggle the highlighting state by
+" using ToggleSpaceHi(). By default, ToggleSpaceHi is bound to the key F3.
+"
+" You can customize the colors by setting the following variables to a string
+" of key=val that would normally follow "highlight group" command:
+"
+"       g:spacehi_spacecolor
+"       g:spacehi_tabcolor
+"
+" The defaults can be found in the "Default Global Vars" section below.
+"
+" You can give a list of filetypes to exclude 
+"
+" If you want to highlight tabs and trailing spaces by default for every file
+" that is syntax highlighted, you can add the following to your vimrc:
+"
+"       autocmd syntax * SpaceHi
+"
+" The author currently uses the following (a little overboard) in his vimrc:
+"
+"   autocmd BufNewFile,BufReadPost,FilterReadPost,FileReadPost,Syntax * SpaceHi
+"   au FileType help NoSpaceHi
+
+" Section: Plugin header {{{1
