But there's generally no need to easily have a look into a .class file
with a tool the user
is used to whereas for python, we're often interested in knowing the
details. And having
a zip file in my way to the source has left me frustrated often enough.
If you want to be consequent and consistent leave out the .py files from
eggs, a jar file
normally doesn't contain .java sources files either.

I agree that they are not system packages, but I would have prefered to
install multiple versions
of a package to separate "site-packages" directories, something that is
really well understood by
most unsofisticated python programmers. The selection of the version
could then be made at
runtime by a PYTHONPATH setting and not by fiddling with .pth files
(something that could
be autmated by a tool and persisted in batch files).
