[Scons-users] Is it possible to use Copy Action Functions outside of SConscript?

[Bill Deegan]

>From manpage:

Builder methods that can be called without an explicit environment may be
called from custom Python modules that you import into an SConscript file
by adding the following to the Python module:

from SCons.Script import *
