I think so, I have created a branch, which shows the Python.Value call
https://github.com/flashpixx/Storage/tree/Python.Value/Scons

The SConstruct runs first the "clone" builder, after that the pull, but the pull isn't working (the message isn't shown)
in the site_scons/site_tools/Repository.py the line 95 is modified, I have added the target_factory.

Is the implementation if my builder correct?

Thanks

Phil
