The cmd2 project is in the process of rapidly stabilizing, but it isn't quite there yet.

The other cmd2 core maintainers and I do have a bunch of refactoring planned over the next 6 to 8 months or so.  Right now @kotfu (Jared Crapo) is working on replacing pyparsing with shlex.  Since shlex is built into Python, that removes one 3rd party dependency.   In early September we plan on abandoning support for Python 2.7 for future releases which will enable us to remove dependencies on most of the other 3rd party libraries we currently depend upon and to dramatically clean the code up in numerous other ways.  The one third party dependency which will be left is pyperclip, but honestly that isn't very well maintained and I've been thinking about removing the functionality we use it for (clipboard copy/paste).

Another core cmd2 maintainer, @kmvanbrunt (Kevin Van Brunt) has been toying with the idea of forking it and creating a lighter and simpler version with a reduced feature set.  If it is something the core developers view as desirable, I think it would perhaps be a viable path forward to have the cmd2 maintainers take over maintenance of cmd and to move towards that becoming the lightweight reduced feature set version and cmd2 living on as the heavier weight more full featured extension of cmd (but many of the current features of cmd2 could be merged into cmd).
