+" Vim syntax file
+" Language:    INTERCAL
+" Maintainer:  Stefan O'Rear <stefanor@cox.net>
+" Last Change: 2008 Nov 29
+" Remark:      Use the Power of Vim to turn your INTERCAL programs into angry
+"               fruit salad.
+"
+" How to use this:
+" * Put levdes.vim (this file) under ~/.vim/syntax (or similar directory for
+"   your system - usually C:\Program Files\Vim\vimfiles\syntax on Windows).
+" * In your .vimrc, add this line: 
+"     au BufRead,BufNewFile *.i set syntax=intercal
+" Thereafter, any .i files you edit in (g)vim will use syntax highlighting.
