zodbpickle presents a uniform pickling interface for ZODB:
- Under Python2, this package forks both Python 2.7's pickle and cPickle
  modules, adding support for the protocol 3 opcodes. It also provides a new
  subclass of bytes, zodbpickle.binary, which Python2 applications can use to
  pickle binary values such that they will be unpickled as bytes under Py3k.
- Under Py3k, this package forks the pickle module (and the supporting C
  extension) from both Python 3.2 and Python 3.3. The fork add support for the
  noload operations used by ZODB.
