First of all, I certainly don't want to prevent Travis from recovering
something for all the effort he has put into scipy_core. Nor do I wish
to discourage anyone that wishes to provide alternative free 
if they so choose. But I will note some facts about numarray 
below that may prove useful to anyone considering the latter.

The numarray User's Manual was derived from the Numpy manual that LLNL
originally sponsored David Ascher to write (if that is incorrect I'm 
Paul will correct me). We dutifully propagated the legal notice in the
original to the numarray version. Although IANAL I'll note that the
text seems to permit changes by others, but it also seems mis-worded as
it refers to software, not documentation regarding the rights. What that
really means in the end I'm not sure.

In any case, Jochen Kupper (I hope I have that right) converted the 
from Framemaker to the Python document latex style. The source for the
numarray version is currently on sourceforge (under the numarray/doc
directory). I'll also note much of the capabilities in scipy_core are
very similar to those of numarray. There are differences, though I don't
believe it would take a great deal of work to udpate the numarray 
to reflect these (e.g. the changes in the types system, how rank-0
issues, the C-API, object array details and the names of the standard
packages within scipy_core.)

 From what I've seen of it, I don't believe it is based at all on the
original manual or any derivative, but I'll leave that for Travis to
comment further on.
