I meant that we should assume that jam has been already built in the current
working copy and invoke that binary. This way we'll be sure that we test
against the version of jam that is in CVS.

Is it possible to reconcile you bat file with approach I propose above? Is
there any reason why tests can't execute bjam binary directly?

Yep... trailing whitespaces are terrible in general.

Okay... I'll apply it and then will write a wrap project-test1.jam in a test
which will just check the output.

Strange! Are you sure that the "test2" directory really exists? I'm using
Windows 2000 and Python 2.2 and t.set_tree("test2") calls works OK. There are
problems later, however, which I will investigate later this day.

I understand and hope to gradually improve usability.
