" Vim syntax file
" Language: Perl POD format
" Maintainer: vim-perl <vim-perl@googlegroups.com>
" Previously: Scott Bigham <dsb@killerbunnies.org>
" Homepage: http://github.com/vim-perl/vim-perl
" Bugs/requests: http://github.com/vim-perl/vim-perl/issues
" Last Change: {{LAST_CHANGE}}
" 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
