That is the solution for Item 1 below. Thanks.

I tried to do this but I just don't understand the contents of the
various arguments and what needs to be returned to be able to write the
appropriate method. It would be helpful to my education to see an
example doing it this way (even though I prefer the solution above).

I am not sure what you are asking. I don't think that I want exactly
the line above in my Jamfiles because that would imply that there would
be two different behaviours in my code for the exe rule. Note that I do
build applications with the exe rule that does not require this
generation of *_runner.cpp files from header files, so I am wondering
how would a developer distinguish when a cxxtest application is being
built and when a normal application needs to be built. Please clarify
if I am off-base here.
I think what I would prefer is a new rule that allows me to write
cxxtest_exe FooTS_runner : FooTS.cpp FooTS.h ;
and have it recognize that it is FooTS.h that needs to be used to
generate the FooTS_runner.cpp file.
Just so you know where we are coming from now is that the Imake template
that we use (we actually use two to distinguish between unit and
performance test targets) only takes the test suite name, i.e. FooTS,
and assumes that FooTS.cpp and FooTS.h exist and generate all the
necessary make targets from that.
