This package intends to provides a compatibility layer for Python between its \
two version release. The future and past packages are both provides for backports \
and forwards, in which you are able to use a single, clean codebase to run under \
Python2/3 environmets easily. With also providing futurize and pasteurize scripts, \
you can convert you Python code to support both version.
