          %%% The parameters used in this configuration file are explained in more detail
          %%% in the ejabberd Installation and Operation Guide.
          %%% Please consult the Guide in case of doubts, it is included with
          %%% your copy of ejabberd, and is also available online at
          %%% http://www.process-one.net/en/ejabberd/docs/

          %%% This configuration file contains Erlang terms.
          %%% In case you want to understand the syntax, here are the concepts:
          %%%
          %%%  - The character to comment a line is %
          %%%
          %%%  - Each term ends in a dot, for example:
          %%%      override_global.
          %%%
          %%%  - A tuple has a fixed definition, its elements are
          %%%    enclosed in {}, and separated with commas:
          %%%      {loglevel, 4}.
          %%%
          %%%  - A list can have as many elements as you want,
          %%%    and is enclosed in [], for example:
          %%%      [http_poll, web_admin, tls]
          %%%
          %%%  - A keyword of ejabberd is a word in lowercase.
          %%%    Strings are enclosed in "" and can contain spaces, dots, ...
          %%%      {language, "en"}.
          %%%      {ldap_rootdn, "dc=example,dc=com"}.
          %%%
          %%%  - This term includes a tuple, a keyword, a list, and two strings:
          %%%      {hosts, ["jabber.example.net", "im.example.com"]}.
          %%%
