ATP>help
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 showing the available
options by entering a '?'.
Three styles of help are provided:
1. Member commands list help is provided when typing the '?'
only or after a group command( e.g. '?', 'dis ?', ) then
the member commands will be listed.
2. Matched commands list help is provided when typing the '?'
after a string( e.g. 'dis?', 'dis l?' ) then the matched
commands will be listed.
3. Command use help is available when typing the '?' after a
full command ( e.g. 'dis log ?' ) and then the usage of
the command usage will be shown up.
