I don't fully understand the goal here.  From later discussion, I think
you envision a model where people drop eggs into some directory and an
application should be able to analyze this directory to determine
which ones to use, meaning which to include in some working set.
In addition to automatically determining the working
set, the application should be able to find the entry points in that
working set.

Does that capture what you want to do?
