Ahh... :-) This is a very, very good idea. But, it might take some
ironing out. I think a copy of what is currently in Numeric is a good

Do you need the history of the CVS repository? If so, Joe has worked
out cvs2svn issues and may be able to help you convert over. Or, you
could just import the latest copy into newcore/f2py and go from there.

I like the vision you've put forward. In the meantime, it would be
good to have something that installs well. I'd really, really like to
get a new download available by the scipy conference. So, if
scipy.distutils is not ready for that, then, I'm going to move ahead
with the more mundane approach I've outlined...
I could use help on configuration to use blas for the new system when
appropriate... Numeric has a manual system that isn't too bad, but I'm
wondering if with scipy.disutils we can automate it somewhat...
