+"	sudo.vim:  A vim plugin by Rich Paul (vim@rich-paul.net)
+"	
+"	This script eases use of vim with sudo by adding the ability to
+"	edit one file with root privleges without running the whole 
+"	session that way.
+"
+"
+"	Usage:  put it in the plugin directory, and
+"			(command line): vim sudo:/etc/passwd
+"			(within vim):   :e sudo:/etc/passwd
+"
+"		sudo will ask for your password if need be.
+"	Requires:
+"		sudo package installed
+"		decent OS (sorry, no windows, unless cygwin has sudo now?)
+"	Provides:
+"		URL handler, sudo: scheme
+"		2 autocommands
+"		
+"	Commands:
+"		SudoRead
+"		SudoWrite
+"	ToDo:
+"		Allow one to sudo to users other than root.
+"		Quote the file name better.
