+=head2 Runtime Configuration
+
+Apart from configuring which FAQ(s) to post you may (re)set some
+runtime configuration variables via the .rcfile (by default
+F<.yapfaqrc>). F<.yapfaqrc> must contain one definition in the form of
+I<param = value> on each line; everything after a "#" sign is ignored.
+
+If you omit some settings they will be set to default values hardcoded
+in F<yapfaq.pl>.
+
+B<Please note that all parameter names are case-sensitive!>
+
+=over 4
+
+=item B<NNTPServer> = I<NNTP server> (mandatory)
+
+Host name of the NNTP server to post to. Must be set (or omitted; the
+default is "localhost"); if set to en empty string, B<yapfaq> falls
+back to Perl's build-in defaults (contents of environment variables
+NNTPSERVER and NEWSHOST; if not set, default from Net::Config; if not
+set, "news" is used).
+
+=item B<NNTPUser> = I<user name> (optional)
+
+User name used for authentication with the NNTP server (I<AUTHINFO
+USER>).
+
+This setting is optional; if it is not set, I<NNTPPass> is ignored and
+no authentication is tried.
+
+=item B<NNTPPass> = I<password> (optional)
+
+Password used for authentication with the NNTP server (I<AUTHINFO
+PASS>).
+
+This setting is optional; it must be set if I<NNTPUser> is present.
+
+=item B<Sender> = I<Sender header> (optional)
+
+The Sender header that will be added to every posted message.
+
+This setting is optional.
+
+=item B<ConfigFile> = I<configuration file> (mandatory)
+
+The configuration file defining the FAQ(s) to post. Must be set (or
+omitted; the default is "yapfaq.cfg").
+
+=item B<UsePGP> = I<whether to add a digital signature> (optional)
+
+Boolean value (0 or 1) controlling whether the FAQs will get digitally
+signed via an X-PGP-Sig header.
+
+This setting is optional; the default is 0.
+
+If you have set I<UsePGP> to 1, you must also supply the necessary
+information on your PGP oder GPG installation; please refer to the
+sample F<.yapfaqrc> file (see below) for more information on this
+topic.
