Subject: Convert the manpage to AsciiDoc

Writing DocBook XML by hand is an awful experience and the tools aren't
much better.  Asciidoctor does it well.  There's no need to worry about
semantics, man(1) just needs to be able to show something at all.

This project's manpage is sadly almost useless right now.
