1.0.4

Fixed reference to Arguments package.

1.0.3

Added ability for long running commands to return a result that indicates that they have started (but aren't done yet).

The main thread then runs dispatch_main() - which never returns. When the command finally finishes, it calls shell.exit() to actually return a result and quit.

1.0.2

Combined various documentation properties into a Description struct.

1.0.1

If a registered command has no name, treat it as the default thing to run if the user doesn't specify a command when invoking the shell.

(If multiple registered commands have no name, the first one wins and the others are ignored).

1.0.0

Initial version lifted from ReleaseTools project.
