SimFactory currently provides a single help screen when you type "sim help". I would like to be able to do "sim help <command>" and get help which is relevant for that command. This help should say briefly what the command does, and give a comprehensive list of the options specific to that command. The top-level "sim help" command should then give a list of the commands, and a list of the simfactory options which apply to all commands. This first help page should be kept as brief as possible so that it is easy to see at a glance what commands are available. The most common commands should be listed first, and maybe separated from the less common commands.
I think this is important as it is the first port-of-call when someone wants to know how to use a particular feature, especially when the syntax is similar but not quite the same as in SimFactory 1.
