Actually, I don't think this is that bad.  Companies have rules; one
simply has to learn to live with this or suffer greatly.  Some rules
are worth fighting, but this probably isn't one of them.

Yes, this is the way it's usually done.  Supposedly Microsoft did this
for a while, after acquiring some Python software.  In the Python 3.4
case, the pyc's should be in the __pycache__ subdirectory.

Another option would be to convert to Cython and compile (not as bad
as it sounds).  But __pycache__/*.pyc would probably be easier.
