On ubuntu/debian install these tools...

python release/test/pep8.py
This searches for the comments "# <pep8 compliant>" and "# <pep8-80 compliant>", running the checking tools on these scripts only.
* some minor pep8 corrections too.
* optional default blend argument, use for better leg & arm defaults
* way to define arbitrary options for bones that can then be passed to the generator function, only used to set elbow target parent at the moment.
