[Ironpython-users] Community Meeting

[Uncle Meat]

OK, I was able to track down some source code for the NumpyDotNet project.
It looks like some people did a lot of work on this:
https://github.com/numpy/numpy-refactor
I'm not sure what state it's in or even if it builds. I'm not sure who did
the .NET portion (I think it was Enthought) but it looks like the
"refactor" branch includes/inherits the numpy license.
