Usage Guidelines

Help may be requested at any point in a command by entering a question mark `?'. If nothing matches, the help list will be empty and you must back up until entering a `?' shows the available options. Two types of help are available

1. Full help is available when you are ready to enter a command argument (for example show ?) and describes each possible argument.

2. Partial help is provided when an abbreviated argument is entered and you want to know what arguments match the input (for example show pr?).
