Your feedback is essential. We want to minimize confusion. There are a
lot of people we are trying to bring together and they all have their
"way to view" the situation. No doubt there are still confusions.

No. These are useless for the new scipy (they won't even be looked
at). They have become

What you have now is officially called scipy_core (that's it's package
name). Sometimes it's referred to as SciPy Core or just Core between
SciPy Core is a replacement for all of Numeric (and for most of
numarray. There are a few numarray packages that are not included in
scipy core --- not sure if these will ever be part of the core or just
add-ons --- that will have to be decided.
Numeric included some basic fft, linear algebra, and random number
routines. These (and a bit more) are all included in scipy core and can
be referenced as
If you install full scipy then scipy.fftpack and scipy.linalg become
the expanded versions with expanded and better functionality based on
FORTRAN interfaces. The basic versions are always available under
scipy.basic.linalg and scipy.basic.fftpack if you want to only ever use
the scipy core version.
This approach allows you to use scipy.linalg.inv and have it map to the
scipy_core version if that's all the user has installed or the full
scipy version if that's what the user has installed.
