sub-module support

[Saravanan Shanmugham (sarvi)]

Hg Forest and git sub-modules are features that essentially allow me to
manage and version those sets conveniently. 

Considering, there is actually a sub-module and forest feature, tells me
the problem I am explaining is not unique ot me. From my reading, I
atleast know the JDK and Open Solaris Teams are interested in the forest
extension.

     Cool.

     Indeed.

     You'll have to manage the sets/collections of the modules 
     regardless of what approach you take.  So, I'm still 
     unclear on exactly what feature the submodules support buys you.
