" Vim syntax file
" Language:    IDL (Interface Description Language)
" Created By:  Jody Goldberg
" Maintainer:  Michael Geddes <vim@frog.wheelycreek.net>
" Last Change:  2012 Jan 11


" 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.

" There are some Microsoft extensions to idl files that are here.  Some of
" them are disabled by defining idl_no_ms_extensions.
"
" The more complex of the extensions are disabled by defining idl_no_extensions.
"
" History:
" 2.0: Michael's new version
" 2.1: Support for Vim 7 spell (Anduin Withers)
