+GeographicLib is a small C++ library for: geodesic and rhumb line
+calculations; conversions between geographic, UTM, UPS, MGRS,
+geocentric, and local cartesian coordinates; gravity (e.g., EGM2008)
+and geomagnetic field (e.g., WMM2020) calculations.
+
+The emphasis is on returning accurate results with errors close to
+round-off (about 5–15 nanometers). Accurate algorithms for Geodesics
+on an ellipsoid of revolution and Transverse Mercator projection have
+been developed for this library. The functionality of the library can
+be accessed from user code or from the Utility programs provided.
+
+This library is not a general purpose projection library nor does it
+perform datum conversions; use PROJ instead.
+
+
+NOTE - This SlackBuild installs the following data sets: egm96-5
+(geoid), egm96 (gravity) and wmm2020 (magnetic), provided that they
+have been downloaded and placed in the SlackBuild's directory, along
+with the source tarball. Several other data sets are available on the
+project's website, or can be downloaded and installed automatically
+by using the following scripts, after installation of the package:
+
+  /usr/sbin/geographiclib-get-geoids
+  /usr/sbin/geographiclib-get-gravity
+  /usr/sbin/geographiclib-get-magnetic
