Convert the parameters passed to SConscript() calls into a list
of files and export variables. If the parameters are invalid,
throws SCons.Errors.UserError. Returns a tuple (l, e) where l
is a list of SConscript filenames and e is a list of exports.

directly so that the proxy can override the subst() method and
