I use pandoc with some Make scripts to generate the epub of my novels and short stories. Having a reproducible way to iterate from source to final docs during edits and correction passes is amazing. I can't imagine doing it any other way.
I was in the same scene (Clan PlanetFortress FTW). Robin and those guys saved us from the annoying cheaters that were exploiting the old qw code. I was so excited for them when they got hired by Valve to make TFC and then HL2.
