sidenote: Reuben refers to the error message that appears when one
enters a non-existent subcommand.
I did get rid of it accepting upper-case subcommands. It's just an
oversight that they still appear. As for other aliases, how about
simply removing them... find the best name for a subcommand, and stick
with it? Else, what's the point of the alias if we are not going to
document it?
