COMMAND: channels
ARGUMENTS: [<channel> [action],...] or [usage]

Simply using the "channels" command without any arguments will display a list
of all channels available to you at the moment, and a brief description of
them, as well as your filter setting for that channel.

If given just a channel name, the command displays the setting for that
channel.  A second argument, if used in addition to a channel name, will set
that channel to a certain filter level.  Valid values are 1-9 (developer
levels), off, and on.  You can also use "list [idle time]" as a second argument
to get a list of the users currently listening to that channel (if you specify
an idle time, your list will only include users that are connected and idle
less than that number of minutes).

When setting channels, you can use "all" as the second argument to set all
channels to the specified setting.

Multiple actions can be specified, separated by a comma.

If the only argument supplied is "usage", then channel usage statistics for the
current month will be displayed.
