True, but merging unrelated branches for a project the size of Aquaria
may be a bit daunting.  (Perhaps not at the moment, since there haven't
been too many commits on icculus.org, but that was my thinking.)

I didn't consider it feasible to use a clone of icculus.org, for various
and sundry reasons but mostly due to the volume of changes I've been
making:

$ hg diff --git -r icculus:tip | wc -l
158206
