+=head1 NAME
+
+virtlockd - libvirt lock management daemon
+
+=head1 SYNOPSIS
+
+B<virtlockd> [ -dv ] [ -f config_file ] [ -p pid_file ]
+
+B<virtlockd> --version
+
+=head1 DESCRIPTION
+
+The B<virtlockd> program is a server side daemon component of the libvirt
+virtualization management system that is used to manage locks held against
+virtual machine resources, such as their disks.
+
+This daemon is not used directly by libvirt client applications, rather it
+is called on their behalf by B<libvirtd>. By maintaining the locks in a
+standalone daemon, the main libvirtd daemon can be restarted without risk
+of loosing locks.  The B<virtlockd> daemon has the ability to re-exec()
+itself upon receiving SIGUSR1, to allow live upgrades without downtime.
+
+The virtlockd daemon listens for requests on a local Unix domain socket.
+
+=head1 OPTIONS
+
+=over
+
+=item B<-d, --daemon>
+
+Run as a daemon & write PID file.
+
+=item B<-f, --config> I<FILE>
+
+Use this configuration file, overriding the default value.
+
+=item B<-p, --pid-file> I<FILE>
+
+Use this name for the PID file, overriding the default value.
+
+=item B<-v, --verbose>
+
+Enable output of verbose messages.
+
+=item B<    --version>
+
+Display version information then exit.
+
+=back
+
+=head1 SIGNALS
+
+On receipt of B<SIGUSR1> virtlockd will re-exec() its binary, while
+maintaining all current locks and clients. This allows for live
+upgrades of the virtlockd service.
+
+=head1 FILES
+
+=head2 When run as B<root>.
+
+=over
+
+=item F<SYSCONFDIR/virtlockd.conf>
+
+The default configuration file used by virtlockd, unless overridden on the
+command line using the B<-f>|B<--config> option.
+
+=item F<LOCALSTATEDIR/run/libvirt/virtlockd-sock>
+
+The sockets libvirtd will use.
+
+=item F<LOCALSTATEDIR/run/virtlockd.pid>
+
+The PID file to use, unless overridden by the B<-p>|B<--pid-file> option.
+
+=back
+
+=head2 When run as B<non-root>.
+
+=over
+
+=item F<$XDG_CONFIG_HOME/virtlockd.conf>
+
+The default configuration file used by libvirtd, unless overridden on the
+command line using the B<-f>|B<--config> option.
+
+=item F<$XDG_RUNTIME_DIR/libvirt/virtlockd-sock>
+
+The socket libvirtd will use.
+
+=item F<$XDG_RUNTIME_DIR/libvirt/virtlockd.pid>
+
+The PID file to use, unless overridden by the B<-p>|B<--pid-file> option.
+
+=item If $XDG_CONFIG_HOME is not set in your environment, libvirtd will use F<$HOME/.config>
+
+=item If $XDG_RUNTIME_DIR is not set in your environment, libvirtd will use F<$HOME/.cache>
+

+
+=head1 EXAMPLES
+
+To retrieve the version of virtlockd:
+
+ # virtlockd --version
+ virtlockd (libvirt) 1.1.1
+ #
+
+To start virtlockd, instructing it to daemonize and create a PID file:
+
+ # virtlockd -d
+ # ls -la LOCALSTATEDIR/run/virtlockd.pid
+ -rw-r--r-- 1 root root 6 Jul  9 02:40 LOCALSTATEDIR/run/virtlockd.pid
+ #
+
