| " 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 |
