I don't think that deprecating 'unit-test' would be a good idea. The 
thing is that it looks consistent with the other rules like exe or lib. 
I've never used 'run' because thanks to its similarity with the main 
targets, 'unit-test' looked like the right way to go.

Actually, I'd be interested to know if it would be possible to integrate 
unit testing even more into the build process. For example when I have a 
cpp file and a test for this cpp file - would it be possible to include 
the corresponding obj file into anything only after the test has 
successfully passed?
