 to convert it to the new YAML format using \term{convert\_to\_yaml} command
 from \term{ejabberdctl} (see~\ref{ejabberdctl} and \ref{list-eja-commands} for details).
 
+If you want to specify some options using the old Erlang format,
+you can set them in an additional cfg file, and include it using
+the \option{include\_config\_file} option, see \ref{includeconfigfile}
+for the option description and a related example in \ref{accesscommands}.

+If you just want to provide an erlang term inside an option,
+you can use the \term{"> erlangterm."} syntax for embedding erlang terms in a YAML file, for example:
