%%% An ejabberdctl command is an abstract function identified by a
|
|
|
|
%%% name, with a defined number of calling arguments, that can be
|
|
|
|
%%% defined in any Erlang module and executed using ejabberdctl
|
|
|
|
%%% administration script.
|
|
|
|
%%%
|
|
|
|
%%% Note: strings cannot have blankspaces
|
|
|
|
%%%
|
|
|
|
%%% Does not support commands that have arguments with ctypes: list, tuple
|
|
|
|
%%%
|
|
|
|
%%% TODO: Update the guide
|
|
|
|
%%% TODO: Mention this in the release notes
|
|
|
|
%%% Note: the commands with several words use now the underline: _
|
|
|
|
%%% It is still possible to call the commands with dash: -
|
|
|
|
%%% but this is deprecated, and may be removed in a future version.
