" Vim syntax file
" Language: configure.in script: M4 with sh
" Maintainer: Christian Hammesr <ch@lathspell.westend.com>
" Last Change: 2008 Sep 03
" Well, I actually even do not know much about m4. This explains why there
" is probably very much missing here, yet !
" But I missed a good hilighting when editing my GNU autoconf/automake
" script, so I wrote this quick and dirty patch.
" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
syntax clear
elseif exists("b:current_syntax")
finish
endif
