Hi Zhon,

sorry for later reply.

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 
rule.

But if you get the current version from CVS, or nightly build from 
http://boost.org/boost-build2, 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?
