I have the following Jamfile for my unit test

import testing ;

unit-test example-test
:   [ glob *.cpp ]
;

install . : example-test ;

It installs example-test.passed into the local directory, instead of the
example-test binary

...patience...

common.copy foo/test/example-test.passed
...updated 1 target...

How can I get it to install the binary instead of the tests passed marker
file?
