Comment 6 for bug 1290018

Cliff does not impose a number of limits on the words in a command -- it takes the name registered and splits it into words and then requires that all of those words be provided on the command line. The custom command manager from rackspace is scanning the filesystem directly (instead of using entry points), and so to prevent recursing too far it looks like they do impose a 3 level structure. They load those commands into a command manager that has a nested structure, but if you're using the entry point based manager native to cliff you don't need that because cliff will do the lookup for you.

Do you have some sample code that shows what you are trying to do and that is not working? Maybe that would help me understand better.
