Running tests with test coverage enabled

Hi all,

Right now I'm running unit tests using Fukamachi's prove library: (asdf/operate:test-system 'my-system).

I want to run my tests generating the tests coverage of my system.

For this I would like to have similar operation, but which will: 1) turn on the code coverage in LispWorks (just call to some global function) 2) rebuild system which I want to test (in this case my-system), but only (!) this system (not dependencies) 3) run tests 4) call coverage results processing function. 5) on normal run (asdf/operate:test-system 'my-system) rebuild the system without coverage.

How could I proceed with this task?
