Extending the OpenStack command line interface

OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed and provisioned through APIs with common authentication mechanisms. OpenStack is broken up into services to allow you to plug and play components depending on your needs. Each of these services comes with its own client tools that usually have more functionality than the main OpenStack command. The goal is to be able to support more of the sub-module functionality inside OpenStack client tools. We want to understand the logic behind the existing commands to try and figure out a general solution on how to do so.
