[Scons-users] SCons.Node.Python.Value on target_factory

[Bill Deegan]

Seems like you should specify the target_factory as Dir, and the
source_factory as a Value if the action is a git pull?

Regardless, when trying to understand such logic, you're always better off
to make a simple single file SConstruct and get it working the way you
expect.
Even make the action just an echo of source and target..

Can you paste an example invocation of your GitPull builder?
