+== NAME
+
+uuidd - UUID generation daemon
+
+== SYNOPSIS
+
+*uuidd* [options]
+
+== DESCRIPTION
+
+The *uuidd* daemon is used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUIDs, in a secure and guaranteed-unique fashion, even in the face of large numbers of threads running on different CPUs trying to grab UUIDs.
+
+== OPTIONS
+
+*-C*, *--cont-clock*[=_time_]::
+Activate continuous clock handling for time based UUIDs. *uuidd* could use all possible clock values, beginning with the daemon's start time. The optional argument can be used to set a value for the max_clock_offset. This gurantees, that a clock value of a UUID will always be within the range of the max_clock_offset.
++
+The option '-C' or '--cont-clock' enables the feature with a default max_clock_offset of 2 hours.
++
+The option '-C<NUM>[hd]' or '--cont-clock=<NUM>[hd]' enables the feature with a max_clock_offset of NUM seconds. In case of an appended h or d, the NUM value is read in hours or days. The minimum value is 60 seconds, the maximum value is 365 days.
+
+*-d*, *--debug*::
+Run *uuidd* in debugging mode. This prevents *uuidd* from running as a daemon.
+
+*-F*, *--no-fork*::
+Do not daemonize using a double-fork.
+
+*-k*, *--kill*::
+If currently a uuidd daemon is running, kill it.
+
+*-n*, *--uuids* _number_::
+When issuing a test request to a running *uuidd*, request a bulk response of _number_ UUIDs.
+
+*-P*, *--no-pid*::
+Do not create a pid file.
+
+*-p*, *--pid* _path_::
+Specify the pathname where the pid file should be written. By default, the pid file is written to _{runstatedir}/uuidd/uuidd.pid_.
+// TRANSLATORS: Don't translate _{runstatedir}_.
+
+*-q*, *--quiet*::
+Suppress some failure messages.
+
+*-r*, *--random*::
+Test uuidd by trying to connect to a running uuidd daemon and request it to return a random-based UUID.
+
+*-S*, *--socket-activation*::
+Do not create a socket but instead expect it to be provided by the calling process. This implies *--no-fork* and *--no-pid*. This option is intended to be used only with *systemd*(1). It needs to be enabled with a configure option.
+
+*-s*, *--socket* _path_::
+Make uuidd use this pathname for the unix-domain socket. By default, the pathname used is _{runstatedir}/uuidd/request_. This option is primarily for debugging purposes, since the pathname is hard-coded in the *libuuid* library.
+// TRANSLATORS: Don't translate _{runstatedir}_.
+
+*-T*, *--timeout* _number_::
+Make *uuidd* exit after _number_ seconds of inactivity.
+
+*-t*, *--time*::
+Test *uuidd* by trying to connect to a running uuidd daemon and request it to return a time-based UUID.

+
+== EXAMPLE
+
+Start up a daemon, print 42 random keys, and then stop the daemon:
+
+....
+uuidd -p /tmp/uuidd.pid -s /tmp/uuidd.socket
+uuidd -d -r -n 42 -s /tmp/uuidd.socket
+uuidd -d -k -s /tmp/uuidd.socket
+....
+
+== AUTHOR
