If you know "how to make headings and links and etc..." then just do that. Save your Perl script or module or whatever it is you're writing the POD as part of. Then just run:

perldoc my_file_name
[download]

For example, I put POD in a script I call dtach.pl. From the command line, I just type:

perldoc dtach.pl
[download]

And the POD is displayed nice and formatted as perldoc pages.

If you're looking for something else, there are a bunch of pod2xxx utilities, where xxx = html, ps, man, etc... to convert POD to output files of the specific utility's type. I use pod2html pretty regularly to post POD pages on my web site.
