[Scons-users] using scons api without invoking main "scons" executable

[William Deegan]

Karl,

Several people have asked this before, however we don't currently support such.
The internal API's are subject to change without notice.
That said they've been fairly stable for a while.
But we do plan some major refactoring of internals going forward.
