" Vim syntax file
" Language: Perl POD format
" Maintainer: Scott Bigham <dsb@cs.duke.edu>
" Last Change: 2001 May 09
" To add embedded POD documentation highlighting to your syntax file, add
" the commands:
"
" syn include @Pod <sfile>:p:h/pod.vim
" syn region myPOD start="^=pod" start="^=head" end="^=cut" keepend contained contains=@Pod
"
" and add myPod to the contains= list of some existing region, probably a
" comment. The "keepend" flag is needed because "=cut" is matched as a
" pattern in its own right.
" Remove any old syntax stuff hanging around (this is suppressed
" automatically by ":syn include" if necessary).
" 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
