Perry,

It would be helpful if you gave some indication of your organization's 
intention with respect to numarray.

Will it be maintained, as in the past, fully in the public domain and 
without charge for either the code or the API information needed to make 
use of the code?

New versions have been produced every few months, will this continue?
