" 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).
" quit when a syntax file was already loaded
