[Scons-users] Provide default Import to SConscript

[Jonathon Reinhart]

Hua,

If you are importing lots of variables into SConscripts, then you're using
SCons wrong. Most of your variables should probably be construction
variables (in the environment).

I've written many, many SConscripts and I've never used more than 3 or 4
Import() statements in a single SConscript. Before you critique a
long-established framework, you might want to consider if you're using it
inappropriately.
