[Distutils] specifying the shipping of subpackages without their superpackages

[Ronny Pfannschmidt]

Hi,

i recently noticed that shipping a package like 'foo.bar' without also
shipping 'foo' seems to work fine in distutils.

since that would be nice way to ship packages within a namespace i want
to sugest specifying the fact that it works and to clarify how it works.


Regards Ronny
