Maybe the right thing to do is to make the choice of license a
fundamental part of the hierarchy?  That is, we could have:
  
  Core   -- all under BSD license
     Core.Control
     Core.Numeric
     Core.User
     Core.Org
     ...
  
  LGPL   -- all under LGPL license
     LGPL.Control
     LGPL.Numeric
     LGPL.User
     LGPL.Org
     ...
  
  GPL   -- all under GPL license
     GPL.Control
     GPL.Numeric
     GPL.User
     GPL.Org
     ...

And then we can impose restrictions like "Core can only import other
Core libraries", "LGPL can import Core and LGPL but not GPL", etc.

ps We should, of course, be saying 'MIT-style license' instead of 'BSD
license' since some people think of BSD as implying the obnoxious
advertising clause.
