[Scons-users] Provide default Import to SConscript

[Hua Yanghao]

Does anyone know in scons there are ways to implicitly make a object
(e.g. xyz) available for SConscript without explicity Import(xyz)?

Just want to eliminate the annoying repeated Import(xyz) in every
single SConscript.

And what about implicit Return()? e.g. xyz() returns a list of object,
then in every SConscript if the top level SConstruct want to collect
the complete list of object returned from every single SConscript.

For example:
SConscript-1:
Import("xyz")

ret = xyz(...)

Return("ret")

Would ideally become:
SConscript-2:
xyz(...)

Thanks,
Yanghao
