#python_helperObject

Most of the magic in this class happens in the python helper script. The ruby side of this provider knows only enough to translate Chef-style new_resource name+package+version into a request to the python side. The python side is then responsible for knowing everything about RPMs and what is installed and what is available. The ruby side of this class should remain a lightweight translation layer to translate Chef requests into RPC requests to python. This class knows nothing about how to compare RPM versions, and does not maintain any cached state of installed/available versions and should be kept that way.
