right...

I was thinking that I would have a functions like:

site_scons site_init.py ( in a system directory)

import SCons.Script

def EnablePartsExtension():
    import parts
    globals().update(parts.glb.globals)
    # I would probably refactor more into something like
    import parts    
    parts.load() 

SCons.Script.my_stuff = EnablePartsExtension

The only problem with this is that the logic in SCons, if I read it correctly, will load the first site_init.py. So the code would break if the user added there own site_init.py in the directory with the Sconstruct.

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
