+\fBkea\-lfc\fP [\fB\-4**|\fP\-6**] [\fB\-c\fP config\-file] [\fB\-p\fP pid\-file] [\fB\-x\fP previous\-file] [\fB\-i\fP copy\-file] [\fB\-o\fP output\-file] [\fB\-f\fP finish\-file] [\fB\-v\fP] [\fB\-V\fP] [\fB\-W\fP] [\fB\-d\fP] [\fB\-h\fP]
+.SH DESCRIPTION
+.sp
+The \fBkea\-lfc\fP service process removes redundant information from the
+files used to provide persistent storage for the memfile database
+backend. The service is written to run as a stand\-alone process. While
+it can be started externally, there is usually no need to do this. It
+is run periodically by the Kea DHCP servers.
+.SH ARGUMENTS
+.sp
+The arguments are as follows:
+.INDENT 0.0
+.TP
+.B \fB\-4 | \-6\fP
+Indicates the protocol version of the lease files; must be either 4 or 6.
+.TP
+.B \fB\-c config\-file\fP
+Specifies the file with the configuration for the \fBkea\-lfc\fP
+process. It may also contain configuration entries for other Kea
+services. Currently \fBkea\-lfc\fP gets all of its arguments from the
+command line.
+.TP
+.B \fB\-p pid\-file\fP
+Specifies the PID file. When the \fBkea\-lfc\fP process starts, it attempts to
+determine if another instance of the process is already running, by
+examining the PID file. If one is already running, the new process is
+terminated. If one is not running, Kea writes its PID into the PID file.
+.TP
+.B \fB\-x previous\-file\fP
+Specifies the previous or ex\-lease file. When \fBkea\-lfc\fP starts, this is the
+result of any previous run of \fBkea\-lfc\fP; when \fBkea\-lfc\fP finishes,
+it is the result of the current run. If \fBkea\-lfc\fP is interrupted before
+completing, this file may not exist.
+.TP
+.B \fB\-i copy\-file\fP
+Specifies the input or copy of lease file. Before the DHCP server invokes
+\fBkea\-lfc\fP, it moves the current lease file here and then calls
+\fBkea\-lfc\fP with this file.
+.TP
+.B \fB\-o output\-file\fP
+Specifies the output lease file, which is the temporary file \fBkea\-lfc\fP should use to
+write the leases. Once this file is finished writing, it is
+moved to the finish file (see below).
+.TP
+.B \fB\-f finish\-file\fP
+Specifies the finish or completion file, another temporary file \fBkea\-lfc\fP uses
+for bookkeeping. When \fBkea\-lfc\fP finishes writing the output file,
+it moves it to this file name. After \fBkea\-lfc\fP finishes deleting
+the other files (previous and input), it moves this file to the previous
+lease file. By moving the files in this fashion, the \fBkea\-lfc\fP and
+the DHCP server processes can determine the correct file to use even
+if one of the processes was interrupted before completing its task.
+.TP
+.B \fB\-v\fP
+Causes the version stamp to be printed.
+.TP
+.B \fB\-V\fP
+Causes a longer form of the version stamp to be printed.
+.TP
+.B \fB\-W\fP
+Displays the configuration report.
+.TP
+.B \fB\-d\fP
+Sets the logging level to debug with extra verbosity. This is primarily for
+development purposes in stand\-alone mode.
+.TP
+.B \fB\-h\fP
+Causes the usage string to be printed.
+.UNINDENT
+.SH DOCUMENTATION
+.sp
+Kea comes with an extensive Kea Administrator Reference Manual that covers
+all aspects of running the Kea software \- compilation, installation,
+configuration, configuration examples, and much more. Kea also features a
+Kea Messages Manual, which lists all possible messages Kea can print
+with a brief description for each of them. Both documents are
+available in various formats (.txt, .html, .pdf) with the Kea
+distribution. The Kea documentation is available at
+\fI\%https://kea.readthedocs.io\fP\&.
+.sp
+Kea source code is documented in the Kea Developer\(aqs Guide,
+available at \fI\%https://reports.kea.isc.org/dev_guide/\fP\&.
+.sp
+The Kea project website is available at \fI\%https://kea.isc.org\fP\&.
+.SH MAILING LISTS AND SUPPORT
+.sp
+There are two public mailing lists available for the Kea project. \fBkea\-users\fP
+(kea\-users at lists.isc.org) is intended for Kea users, while \fBkea\-dev\fP
+(kea\-dev at lists.isc.org) is intended for Kea developers, prospective
+contributors, and other advanced users. Both lists are available at
+\fI\%https://lists.isc.org\fP\&. The community provides best\-effort support
+on both of those lists.
+.sp
+ISC provides professional support for Kea services. See
+\fI\%https://www.isc.org/kea/\fP for details.
+.SH HISTORY
+.sp
+The \fBkea\-lfc\fP process was first coded in January 2015 by the ISC
+Kea/DHCP team.
