1" Vim syntax file
2" Language:	Perl POD format
3" Maintainer:	Scott Bigham <[email protected]>
4" Last Change:	2005 Jul 05

6" To add embedded POD documentation highlighting to your syntax file, add
7" the commands:
8"
9"   syn include @Pod <sfile>:p:h/pod.vim
10"   syn region myPOD start="^=pod" start="^=head" end="^=cut" keepend contained contains=@Pod
11"
12" and add myPod to the contains= list of some existing region, probably a
13" comment.  The "keepend" flag is needed because "=cut" is matched as a
14" pattern in its own right.
15
16
17" Remove any old syntax stuff hanging around (this is suppressed
18" automatically by ":syn include" if necessary).
19" For version 5.x: Clear all syntax items
20" For version 6.x: Quit when a syntax file was already loaded
21if version < 600
22  syntax clear
23elseif exists("b:current_syntax")
24  finish
25endif
