Standard way to distribute utilities with packages

[Laszlo Nagy]

I'd like to distribute a pure Python package named "foo". By default it
will be placed in lib/site-packages/foo. What if I want to add
utilities? Command line or GUI programs that are not full featured
applications, but they can be handy for some tasks that are related to
the package. Here is what I see:

* Python places them under "tools" in the Python installation dir (under
windows). I'm not sure about Unix.

Other variants:

* site-packages/foo/scripts (example: win32)
* site-packages/foo/util (example: vtk)
* directory site-packages/foo/tools (example: numpy)

Is there a PEP number / standard way for this?

Thanks,

Laszlo
