So I put a lot more time into this today than I really had available.  I
think it's cool stuff, and we definitely want it.  But can I ask for one
more pass?  In particular:

 - It makes the docs build a lot more noisy, that would be nice to fix.

 - A bit more documentation in the script would be nice.  It also is happy
   to run with silly arguments; a detail since nobody will run it
   directly, but still...

 - Most importantly, it breaks "make htmldocs"; in particular, vast
   amounts of error spew results when it gets around to media_api.html.  I
   spent a while trying to figure out what was going on but didn't come up
   with anything conclusive; my suspicion is that it has to do with the
   separate makefile in Documentation/DocBook/media/.

Thanks,
