Er, Zack? I suggest you think twice before saying "shouldn't be hard"
regarding something most of us have carefully avoided, for sanity's
sake. :-)

Seriously: This is something that's fairly easy to hack up, but
excruciatingly difficult to get right.

As I said elsewhere, "svn log" gives you exactly what you want, modulo

The good news is that Subversion can spit the changelogs out in XML
format, and converting those to anything else should be a piece of cake.
