[Scons-users] How to build only a subset of targets under a directory

[Bill Deegan]

I guess I'm not really clear what you want to do.

You could make a PsuedoBuilder (see users guide/manpage) something like

env.TestProgram(...)
And that could add all your tests to an alias progrmatticaly and also pass
the args to Program()..

Would something like that work?
