[Scons-users] Storing object files in different directory

[Gary Oberbrunner]

As the user guide says in sec. 15
(http://www.scons.org/doc/HTML/scons-user/ch15.html) it is much easier
to use SConscript(..., variant_dir=...) than call VariantDir directly.
If you don't want to have a SConscript, but really want to use
VariantDir directly, the example at
http://www.scons.org/doc/HTML/scons-user/ch15s04.html shows some
helpful hints.

And the error message is correct; a build dir can't have two different
source dirs.  What if they had conflicting filenames?
