" Vim syntax file
" Language: IDL (Interface Description Language)
" Maintainer: Jody Goldberg <jgoldberg@home.com>
" Last Change: 2001 May 09
" This is an experiment. IDL's structure is simple enough to permit a full
" grammar based approach to rather than using a few heuristics. The result
" is large and somewhat repetative but seems to work.
" 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
