+== Synopsis ==
++ntpsweep+ [+-l+ 'host']... [-p] [+-m+ 'number'] [+-s+ 'prefix'] [+-h+ 'string']
+
+== Description ==
+
+`ntpsweep` prints per host the NTP stratum level, the clock offset in
+seconds, the daemon version, the operating system and the processor.
+Optionally recursing through all peers.
+
+If no hosts are specified, `ntpsweep` reports on localhost.
+
+`ntpsweep` relies on `ntpq` and Mode 6 queries to probe servers.  This
+depends on the remote host's _restrict_ configuration allowing
+queries. Nowadays effectively all public hosts set _noquery_, so this
+script is unlikely to be useful unless you have multiple specially-
+configured timeservers on a LAN.
+
+== Options ==

++-l+ string, +--host-list+=_string_::
+  Host to execute actions on. This option may appear an unlimited number
+  of times.
