It's easy. Gems can depend on other gems. So we can have some highly 
cohesive and highly coherent gems at the bottom, and then other, more 
application-oriented gems that pull the necessary basic gems together. 
This can be done on more and more levels if necessary.

Composition is a great concept, and applying it recursively is even better.
