" Vim syntax file
" Language: CSP (Communication Sequential Processes, using FDR input syntax)
" Maintainer: Jan Bredereke <brederek@tzi.de>
" Version: 0.6.0
" Last change: Mon Mar 25, 2002
" URL: http://www.tzi.de/~brederek/vim/
" Copying: You may distribute and use this file freely, in the same
" way as the vim editor itself.
"
" To Do: - Probably I missed some keywords or operators, please
" fix them and notify me, the maintainer.
" - Currently, we do lexical highlighting only. It would be
" nice to have more actual syntax checks, including
" highlighting of wrong syntax.
" - The additional syntax for the RT-Tester (pseudo-comments)
" should be optional.
" quit when a syntax file was already loaded
if exists("b:current_syntax")
finish
endif
