I've got lot's of little wx apps we could use -- just tell me where to 
put them.

This is a bit tricky -- MPL uses multiple back-ends, so we might need:

one using wx
one using TK
one using the new Cocoa back-end.

At least we can stick with just numpy now!

Do you have any ideas about how to runs tests automatically? As many of 
these are GUI app issues, it would be nice to be able to test without 
having to do a bunch of point and clicking. Maybe just knowing they 
start without errors is good enough -- particularly if they are written 
so that the toolkit in question is well exercised, by default, at startup.

Also -- any plans to support eggs? I'm using py2app to bundle up a 
Pylons-based app (web framework). It makes heavy use of eggs (and 
pkg_resources, the real problem), and I had to write a lot of extra code 
to get everything I needed included.

It's worth looking at what bb-freeze is doing -- they're using 
modulegraph too. I'd like to see a py2app -- bbfreeze merger, in fact.

It seems the app building process has two distinct parts:

1) figuring out what to include

2) bundling it all up

(1) is pretty platform dependent, so I"d love to see it the same in a 
tool for all platforms.
   -- OK figuring out which shared libs to include is probably platform 
dependent...

(2) is going to b totally different on the different platforms, but 
we've got the basic code on all platforms now anyway.

I say this based on my recent experience bundling a challenging app for 
Mac an Windows -- I used py2exe and py2app. While they both have a 
similar API, as son as I needed to extend what they do on their own, I 
found that I needed to write totally separate code -- I'd love to no 
have to do that!
