How to add to SConscript namespace

SConstruct

env=Environment()

SConscript('src/SConscript',exports='env')

site_scons site_init.py

import SCons.Script

def my_stuff():
    print("BLAH")

SCons.Script.my_stuff = my_stuff

src SConscript

Import('env')

my_stuff()

I wonder if:

import SCons.Script
import parts

parts.setup_stuff(SCons.Script)

Would do what you want.. Then you'd add all the symbols you want available as attributes to the passed object.

Yes that would work, but the user will have little control in being able to selection parts being added or not add to there build when using SCons. The suggestion I made means the user can add it or remove it at the point the Sconstruct is read in.

Ideally having a SCons extension API to allow control over what extensions get loaded or not would probably be better
