+`gpsdLogger` is a [`gpsd`](http://www.catb.org/gpsd/) client which publishes
+Position/Location Information (P/LI) to a shared memory segment, compatible
+with
+[`gpsLogger`](https://downloads.pf.itd.nrl.navy.mil/docs/proteantools/gpsLogger.html)
+and [MGEN](https://www.nrl.navy.mil/itd/ncs/products/mgen).  It does not set
+time, as it is expected that systems using `gpsdLogger` will also use
+[`ntpd`](http://ntp.org/downloads.html) for time management.  (Otherwise,
+`gpsLogger`, without the `d`, is a more suitable program, as it manages time
+and logs P/LI in a single program.)
+
+It was created to address the situation where sole access to a GPS receiver
+could not be ensured, and therefore `gpsd` was used to multiplex GPS data
+access.  Although `gpsd` provides timing information suitable for use with
+`ntpd`, it does not publish P/LI in a format that MGEN can understand.
+Rather than patch MGEN, this utility was designed to emulate `gpsLogger`'s
+shared memory publishing, allowing MGEN to automatically acquire P/LI from
+`gpsd`.
