Thanks, this is a helpful start. Now, when I build the "exe" target,
the executable builds as expected. But when I run the test, the
executable gets deleted, even it was built earlier. I'd like to be
able to invoke bjam a single time, without having to pass
--preserve-test-targets, so that the test is run *and* the executable
is preserved. Is this possible? Put another way, can the run rule make
use of an existing artifact without deleting it, without having to
pass options to bjam?
