" 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.
"
