Command actions (subcommands)

[Gawdl3y]

Commands should be able to define a list of actions that each have their own set of arguments, help info, and other properties. Each action should be its own method on the command's class, and a default should be able to be specified rather than relying on the run method. These need to be properly auto-documented in the default help command.

Would I be correct in assuming that this enhancement has not been implemented?
