+and if necessary, updates leap-second definition file.
+
+Ordinarily, the file is found using the "leapfile" directive in
+@code{ntp.conf(5)}.
+However, an alternate location can be specified on the command line.
+
+If the file does not exist, is not valid, has expired, or is expiring soon,
+a new copy will be downloaded.  If the new copy validates, it is installed and
+NTP is (optionally) restarted.
+
+If the current file is acceptable, no download or restart occurs.

+-c can also be used to invoke another script to perform administrative
+functions, e.g. to copy the file to other local systems.
+.PP
+This can be run as a cron job.  As the file is rarely updated, and leap
+seconds are announced at least one month in advance (usually longer), it
+need not be run more frequently than about once every three weeks.

+
+  <p><code>update-leap</code>
+will validate the file currently on the local system
+and if necessary, updates leap-second definition file.
+
+  <p>Ordinarily, the file is found using the "leapfile" directive in
+<code>ntp.conf(5)</code>. 
+However, an alternate location can be specified on the command line.
+
+  <p>If the file does not exist, is not valid, has expired, or is expiring soon,
+a new copy will be downloaded.  If the new copy validates, it is installed and
+NTP is (optionally) restarted.
+
+  <p>If the current file is acceptable, no download or restart occurs.
+
+  <p>-c can also be used to invoke another script to perform administrative
+functions, e.g. to copy the file to other local systems. 
+.PP
+This can be run as a cron job.  As the file is rarely updated, and leap
+seconds are announced at least one month in advance (usually longer), it
+need not be run more frequently than about once every three weeks. 
+.PP
+For cron-friendly behavior, define CRONJOB=1 in the crontab. 
+.PP
+This script depends on$REQUIREDCMDS
+
+  <p>This section was generated by <strong>AutoGen</strong>,
