The HELP command is used to display every command's name and description
|
||
|
|
to the user, so that he may see what commands are available. The help
|
||
|
|
command is also filtered by level, so if a user does not have access to
|
||
|
|
a command, it is not shown to them. If a command name is given with the
|
||
|
|
help command, its extended help is shown.
