" 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: 2017-09-12 " 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.
