well, I still have problems with import

suppose I have something like this:

M/
  __init__.py
  A/
    __init__.py
    One.py
  B/
    __init__.py
    Two.py

One.py
    #!/usr/bin/python

    from M.B import Two

Two.py
    #!/usr/bin/python

    from M.A import One


when I try to run One.py or Two.py I get import errors and I don't know
how to fix them.  I tried to set the __all__ variable in the __init__
files but nothing worked so far.

I would like to run the files from anywhere for example.
What am I doing wrong?
I read the information about modules on python.org
(http://www.python.org/doc/2.0.1/tut/node8.html) but I don't find a
solution

Thanks
