Well, I am now.  If anyone wants to test, i'm going to make an attempt
to keep the following overlay in sync with the main tree within a
24-hour delay (excluding weekends).

git://git.overlays.gentoo.org/dev/axs.git

FYI, all the work subslotting the perl stuff doesn't work yet, so it's
probably best to wait a few days before trying it out.

Sorry, no means of bug reporting on any of this yet (ie, don't file on
b.g.o about it), but i'm in #-dev on freenode most weekdays.
