-gpsd is a service daemon that monitors one or more GPSes attached to a 
-host computer through serial or USB ports, making all data on the location, 
-course, and velocity available to be queried on TCP port 2947 of the host 
-computer.  With gpsd, multiple GPS client applications (such as navigational 
-and wardriving software) can share access to GPSes without contention or 
-loss of data.  Applications that presently use gpsd include Viking and Kismet.
+gpsd is a service daemon that monitors one or more GPSes attached to
+a host computer through serial or USB ports, making all data on the
+location, course, and velocity available to be queried on TCP port
+2947 of the host computer.  With gpsd, multiple GPS client applications

 See README.build for some additional build options that might be useful.
+
+To enable automatic startup of gpsd at boot time, or when a GPS device is
+connected via USB, you need to do the following three steps:
+
+1. Edit the file /lib/udev/rules.d/97-gpsd.rules and uncomment the line
+(or lines) beginning '#ATTRS' that corresponds to your GPS hardware and
+save it in /etc/udev/rules.d/. To avoid confusion with other USB serial
+devices that you might have, do not uncomment lines that do not
+correspond to your GPS hardware.
+
+2. Make the file /etc/rc.d/rc.gpsd executable.
+   chmod +x /etc/rc.d/rc.gpsd
+
+3. Add the following lines to /etc/rc.d/rc.local
+  if [ -x /etc/rc.d/rc.gpsd ]; then
+    /etc/rc.d/rc.gpsd start
+  fi
+
+Configuration options may be set in the file /etc/rc.d/rc.gpsd.conf.  The
+defaults will usually be adequate.  However, if your GPS is on a real (non-USB)
+serial port -- for example, /dev/ttyS0 -- you should add /dev/ttyS0 to
+GPS_DEVICES in /etc/rc.d/rc.gpsd.conf.
