[Scons-users] SConscripts on the fly

[Eric Lunderberg]

As a potential alternative, if the SConscripts can be automatically
generated from a top-level SConstruct, why not instead generate the build
actions directly?  That way, the intermediate SConscript would not need to
be generated at all.  If some directories require customized behavior, then
those directories could be the only ones that contain a SConscript, and the
top-level SConstruct could preferentially use such a SConscript if it
exists.
