perl-pod-preview.el displays a formatted preview of Perl POD format documentation in a buffer. Get it from
man -l and is geared towards use while editing since it tries to preserve the buffer position when re-running the preview.
CPerlMode has a similar preview using
pod2man, but the single buffer of
perl-pod-preview better suits editing, and
perl-pod-preview can also be used from any buffer, it doesn’t have to be a disk file, which means you can look at formatted POD while browsing a TarMode file for instance.
