1 " Vim syntax file
2 " Language: Perl POD format
3 " Maintainer: Scott Bigham <dsb@killerbunnies.org>
4 " Last Change: 2007 Jan 21
5
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
