Hmm you're right, it leaves no trail for someone to find out how to
run tests in a single module if they don't already know.  Now I'm
inclined to leave that little bit of code there. I'm glad I asked. :)

Since I've been working mostly on the tests, I haven't really had to
cope with that yet.  The install only takes a short time (5-10 sec)
once everything is built, and I don't have to do it that often, but I
can see it would be a bit onerous if I was changing stuff that caused
recompiles, etc.

Is the stuff Robert pointed out on a wiki page somewhere? It would be
nice to have a "Welcome noob NumPy developer, here's how to do
NumPy-specific development things," page. There may be such a page,
but I just haven't stumbled across it yet.
