+To write a logfile, call C<log_add($logtype, $string)>. On the first call,
+this function opens and locks C<$logdir/log>; subsequent calls just append to
+this file. As such, this function is only appropriate for situations where
+C<log_rename> will be invoked later to rename C<$logdir/log> to
+C<$logdir/log.$timestamp.$n>.

+If you need to write a log entry for another program, for example to simulate
+taper entries, call C<log_add_full($logtype, $pname, $string)>.
