I suggest keeping only one setup script, 'setup_xxx.py', per module.

Moving CVS directories is discussed in

  http://www.gnu.org/manual/cvs-1.9/html_node/cvs_69.html

But how desired is that one can retrive older versions of these modules?

It seems that after renaming CVS directories, one looses their commit
history (in the sense of the last sentence in the above link, though
with some hacking on CVSROOT/history file (e.g. changing world/chaco
to world/scipy/chaco) it should be possible to preserve the commit
history, but that is theoretically, I have never done that myself nor do
not know if anyone else have tried that).

Safer approach would be to commit chaco, kiva, freetype modules to SciPy
as new modules while still keeping original chaco and kiva CVS
repositories, but only in read-only mode so that one can still see the
commit history for references.
And later on, when the original chaco and kiva CVS repositories are not
used/needed anymore, they can be simply removed or archived (though, this
will save only 20MB of disk space).


Another question: Do you want to move chaco, kiva, freetype modules before
or after releasing scipy-0.2?
