	Message internationalization: a
	the usage of reply_message_nl()
	</title>

<para>
For the message internationalization, 
use reply_message_nl()
	<footnote>
	<para>
	See FML::Process::Kernel module.
	</para>
	</footnote>
like this:
<screen>
$curproc->reply_message_nl('error.already_member',
			   'already member',
			   { _arg_address => $address });
</screen>
This function uses the message template at
/usr/local/share/fml/$fml_version/message/$language/error/already_member
.
</para>

<para>
$_arg_VARNAME in the message template such as
<screen>
$_args_address
</screen>
is expanded by using the value specified as the argument of
reply_mesage_nl().
</para>

<para>
Usual $VARIABLE is also expaned by replacing it with value of config.cf.
For example, $ml_name is expanded to ML name defined in config.cf.
$_arg_ prefix is used for lexical scope variables to avoid
conflicts against variables in config.cf.
