You should have commit rights now.

I've considered moving the scikit to github, since that seems to be
where everyone else has gone... mostly I haven't bothered because
scikits.sparse hasn't had my attention. So if you have an opinion on
this, speak up :-).

I don't have a strong opinion on this -- I just install suitesparse as
a unit from my package manager, so having them all together is the
easiest thing for me. And I'm very grateful that I don't have to do
the analogue for scipy, installing scipy-blas, scipy-lapack,
scipy-fftpack, scipy-sparse etc. as separate packages :-). But other
systems seem to require much more effort to get their build
environments set up, so perhaps there are people who would find some
sort of separation or partial install feature useful; I just don't
know.
