" 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
