" VIM Syntax file for txr
" Kaz Kylheku <kaz@kylheku.com>

" INSTALL-HOWTO:
"
" 1. Create the directory .vim/syntax in your home directory and
"    put this file there.
" 2. In your .vimrc, add this command to associate *.txr files
"    with the txr filetype.
"    :au BufRead,BufNewFile *.txr set filetype=txr | set lisp
"
" If you want syntax highlighting to be on automatically (for any language)
" you need to add ":syntax on" in your .vimrc also. But you knew that already!
"
" This file is generated by the genvim.txr script in the TXR source tree.
