Right, it builds the "tests" not the "regressions".  You asked for "tests"
not "regressions".

For "tests" and "regressions", run "scons check.

Have at it.  Just run "scons check" first.

Right, it builds the "tests" not the "regressions".  You asked for "tests"

So run it after a clean build, then don't clean.

I'm still unclear what needs "fixing"?  Sounds like maybe a 
feature request for "scons regress-deiver".  If all you want is
regress-driver installed in buildtmp.

I'd rather not have to support all the internal options as an API.  Then
it can not longer be easiely changed.

And we certinaly do not want to make it harder to find the normal user
targers, or confuse users with developer targers.

As Fred suggested: grep for Alias tells you all the targets.

# less SConscript

But you are not going to find what I think you are looking for.  If you
could explain what you want to happen then adding a new target for you
is easy.  But I would rather not document it and then have to explain
to people why it is not what they want.
