Jeff, I have checked in my tests for the acs-lang package. They are in acs-lang/tcl/test.
Pete - one issue to consider with sourcing the test procs is that the bootstrapper currently sources all tcl files ending in (procs|init).tcl even if they are under tcl/test. We should be careful here to not source files twice. I am naming my test file *-test.tcl but I don't know if we want to rely on that convention.
