Use "bjam -n". It will print commands instead of executing them.

Ah, sorry, the working code would be:

make test-runner.cpp : test-file.h : $(__name__).make-test-runner ;
actions make-test-runner
perl make-test-runner -output $(<)

The __name__ is the name of current module, and is used to fully-qualify the

But if you get the current version from CVS, or nightly build from, you'll be able to use my original code
unmodified, and find an example of usage in example/make.

I've just removed the requirements to use fully-qualified name.

Then, what about

unit-test runner1 : dir1/testedfile.cpp ;
unit-test runner2 : dir2/testedfile2.cpp ;

and so on?
