[Scons-users] SCons as a library

[Gary Oberbrunner]

On the general topic of using Sapphire as a library (i.e. directly from an
existing python process), it was never really a design goal for SCons to
work that way; it's optimized as much for people who don't know a lot of
python as it is for python experts (though we've tried to make it useful
for both constituencies of course).  That said, if you look in
SCons/Script/Main you can see how the main script bootstraps itself, reads
the SConstruct, and starts the build.  Getting in at that level is
DEFINITELY not supported, but I believe it can be integrated at that level.
 But don't forget that just popening a subprocess to runs SCons is going to
be way, way, simpler.
