If two or more commands is supposed to perform the same action, currently the whole command (including the action) is duplicated. There should be a way to indicate that several commands perform one action, and have the action code present only once.
An example of that is catfact. There are 4 catfact commands with different spelling, and they all perform the exact same action.
When I make a change to a command, and tell DLB to reload the commands, he tells me the number of commands loaded, but doesn't act differently on the changed command.
