It's funny. I like Python better for various reasons, but I have to admit that Perl 5 always seems to have more mature and far better-documented modules available. You use the Cheeseshop for a while (Python's central package repository) and get used to it, then go back to the CPAN and it's really noticeable how much better the Perl 5 module ecosystem is.
Pandoc is indeed excellent. I suggest that anyone needing to write a man page just write it in Markdown and -- if a man page is necessary -- have Pandoc convert it.
