%%% @doc Administrative functions and commands for ProcessOne customers
%%%
%%% This ejabberd module defines and registers many ejabberd commands
%%% that can be used for performing administrative tasks in ejabberd.
%%%
%%% The documentation of all those commands can be read using ejabberdctl
%%% in the shell.
%%%
%%% The commands can be executed using any frontend to ejabberd commands.
%%% Currently ejabberd_xmlrpc and ejabberdctl. Using ejabberd_xmlrpc it is possible
%%% to call any ejabberd command. However using ejabberdctl not all commands
%%% can be called.
