Thanks for the info, Eric.

Unfortunately, our manpages appear to be generated from some docbook 
file that doesn't appear to exist anymore:

    http://bugzilla.libsdl.org/show_bug.cgi?id=351

We really should move to Doxygen or something, since while having the 
manpages are convenient, they are out of date in some places, competing 
with the wiki, and are yet-another copy that needs to be updated when 
things change. It'd be nice to unify all that.
