'''
The zodbpickle.pickle module exposes the standard behavior of
the pickle module.
This is backward compatible, but has the effect that by default,
on Python3 you get the fast implementation, while on Python2
you get the slow implementation.

This module is a version that always exposes the slow implementation
of pickling and avoids the need to explicitly touch internals.
'''

'''
Note: We are intentionally using "import *" in this context.
The imported modules define an __all__ variable, which contains
all the names that it wants to export.
So this is a rare case where 'import *' is exactly the right thing to do.
