[Module-build-general] Resursive builds?

[David C. <dl...@ha...>]

Back in March there was a discussion about the /lib directory vs. 
EU::MakeMaker's directory structure w.r.t. resursive builds.  Has any
more work been done on recursive builds?  

Actually, I think what I'm mainly interested in is "recursive testing".  
In a distribution which comprises a few levels of class heirarchy, 
it would be very convenient for me to issue a "./Build test" from 
a lower level in the heirarchy and have only the tests relevant to that 
level/class be executed.  Either that, or have the test method know 
about subdirectories in the top-level t/ directory:

    ./Build test test_files=t/Foo/Bar/

run all tests found in .../t/Foo/Bar
