In an earlier message, a workaround was offered specifically for the
case of user commands (“scripts”): don't use entry points, instead make
symlinks from ‘/usr/share/FooApp/lorem/dolor.py’ to ‘/usr/bin/foo’.

That isn't sufficient, for several reasons:

* A ‘console_script’ entry point specifies a specific function within
  the module. Running the module file as ‘__main__’ isn't always a
  replacement for that.

* Distutils clobbers the execute bit on module files when installing
  them, so telling Debhelper to just make a symlink still doesn't result
  in an executable command.

* This doesn't address the problem that ‘pkg_resources’ still can't find
  the application's distribution metadata.

  Other queries to `pkg_resources` for this application's distribution,
  for example to get the distribution version or homepage URL, will also
  fail.

Would it be correct design for Pybuild to place Python libraries in one
location and the Distutils metadata in a different location; the former
private, the latter available at least to the application itself?

I don't quite know how that would work, but it sounds like what I'd
expect if we're going to have sensible “application private modules in
‘/usr/share/FooApp/’ where they aren't public” behaviour.
