of keyids on the command line, fetches them from a keyserver and calls GnuPG so
that you can sign it. It then mails each key to all its email addresses - only
including the one UID that we send to in each mail, pruned from all but self
-sigs and sigs done by you.
+sigs and sigs done by you. The mailed key is encrypted with itself as a means
+to verify that key belongs to the recipient.
=head1 OPTIONS
Don't export UIDs by default, on which your latest signature is older
than this age. Default: B<24*60*60> (i.e. one day).
+=item B<local-user> [string]
+
+Select the key that is used for signing, in case you have more than one key.
+
=head2 Mail settings
=item B<mail> [boolean]
Address to send blind carbon copies to when sending mail.
Default: none.
+=item B<mailer-send> [array]
+
+Parameters to pass to Mail::Mailer.
+This could for example be
+
+ $CONFIG{mailer-send} = [ 'smtp', Server => 'mail.server', Auth => ['user', 'pass'] ]
+
+to use the perl SMTP client or
+
+ $CONFIG{mailer-send} = [ 'sendmail', '-o8' ]
+
+to pass arguments to the sendmail program.
+For more information run C<< perldoc Mail::Mailer >>.
+Setting this option is strongly discouraged. Fix your local MTA
+instead.
+Default: none.
