Hi Andrew,  sorry about not getting back to this sooner.  I actually
committed this some time last week but forgot to follow up on the
e-mail.  Anyway, well done.  Patches that work are one of my favorite
things.

No.  All of the self-tests for numarray, with the exception of the f2py
support, are integrated into numarray.testall.  The tests can always be
improved,  but they are intended to be centralized so that should always
be the only place you have to look.

Thanks again for the patch.

Regards,
Todd
