That makes sense - but as you mention, it seems like there's some
missing functionality.

I don't have time to test, but I think that's been fixed.
However, it's no fun if you have a lot of subpackages to add that way.

For what it's worth, the approach I'm now taking is to create the full
packages for each helper app, then just directly add the missing files
in site-packages.zip and lib-dynload from the helper into the main
app.
Using ZipFile, it's not too bad.

I looked at the source for how py2app uses modulegraph, to see if I
could just generate the dependencies for the sub apps and pass them as
the 'includes' for the main app, but that seemed involved enough that
I ended up doing the above.
