ICE Agent has a special switch, --help, that can be placed anywhere on the command line. When present, it causes ICE Agent to display information about available commands and switches and exit.

While the --help switch can be applied anywhere, the informational text displayed refers to the command or subcommand which received the --help switch. For example, agent --help displays information about commands and switches that can be applied to agent whereas agent external --help rallypoint displays information about the external command. Why show help for the external command and not the rallypoint subcommand? Because the first command appearing to the left of --help is external, not rallypoint.
