+" DrawIt.vim: a simple way to draw things in Vim
+"
+" Maintainer: Charles E. Campbell
+" Authors: Charles E. Campbell <NdrOchipS@PcampbellAfamily.Mbiz> - NOSPAM
+" Sylvain Viart (molo@multimania.com)
+" Version: 13
+" Date: Nov 25, 2013
+"
+" Quick Setup: {{{1
+" tar -oxvf DrawIt.tar
+" Should put DrawItPlugin.vim in your .vim/plugin directory,
+" put DrawIt.vim in your .vim/autoload directory
+" put DrawIt.txt in your .vim/doc directory.
+" Then, use \di to start DrawIt,
+" \ds to stop Drawit, and
+" draw by simply moving about using the cursor keys.
+"
+" You may also use visual-block mode to select endpoints and
+" draw lines, arrows, and ellipses.
