For clarification:  this is in the sample chapter available on-line to

Absolutely.   I did the Numarray page because I'd written a lot on 
Converting from Numeric (even providing convertcode.py) but very little 
for numarray --- except the ndimage conversion.  So, I started the 
Numarray page.   Sounds like a great idea to have a dual page.
