 DESCRIPTION

@@ -28,6 +29,11 @@ useful e.g. for log rotation.
 
 If the child handler exits, *accesslog* exits as well.
 
+Normally, *accesslog* locks the logfile using *fcntl*(2) to ensure
+that only one process writes to a logfile at any time. The *-L* switch
+can be used to override that behavior to let several processes share a
+logfile, or to use logfiles that cannot be locked for some reason.

+*-L*::
+
+	Do not attempt to lock the logfile. Note that this switch
+	conflicts with the use of the *-P* option.
+
+*-P* 'LOGFILE'::
+
+	Makes *accesslog* fetch the PID of the process currently
+	holding the lock on 'LOGFILE', write that to standard output,
+	and then exit. No further command-line arguments are
+	processed. This option is useful for sending SIGHUP to
+	accesslog when rotating logfiles without having to use a PID
+	file.
