+          PPS (Pulse Per Second) is a special pulse provided by some GPS
+          antennae. Userland can use it to get a high-precision time
+          reference.
+
+          Some antennae's PPS signals are connected with the CD (Carrier
+          Detect) pin of the serial line they use to communicate with the
+          host. In this case use the SERIAL_LINE client support.
+
+          Some antennae's PPS signals are connected with some special host
+          inputs so you have to enable the corresponding client support.
+
+          To compile this driver as a module, choose M here: the module
+          will be called pps_core.ko.
+
+config PPS_DEBUG

+        help
+          Say Y here if you want the PPS support to produce a bunch of debug
+          messages to the system log.  Select this if you are having a
+          problem with PPS support and want to see more of what is going on.
