ALso, often the set of dependencies required by the tests are larger  
than the set of dependencies required for the distribution to be  
useful at installation time.  E.g. in one of my distributions, I ship  
a set of ZCML declaration definitions, and my tests need to test it,  
and thus the tests need some ZCML package support to run.  But the  
distribution doesn't actually itself need the same ZCML support  
packages to run, it just needs it to test that, were someone to use  
the ZCML declaration stuff I've created, it would work.
