Amtape was still in C in 2.6.1, and still using the old changer API,
which does not support config overwrites.

I'm *very* excited that you're using these new tools!  They are still
under development, and the old changer API should be removed entirely
by the next release, so you might have better luck using trunk, rather
than the latest release.

Please send along any feedback or requests regarding the interface,
too -- to a point I've been coding in a vacuum so some third-party
criticism would be helpful.
