+Usage:
+    mapcode [-d | --decode] <default-territory-ISO3> <mapcode> [<mapcode> ...]
+
+       Decode a Mapcode to a lat/lon. The default territory code is used if
+       the Mapcode is a shorthand local code
+
+    mapcode [-e | --encode] <lat:-90..90> <lon:-180..180> [territory-ISO3]>
+
+       Encode a lat/lon to a Mapcode. If the territory code is specified, the
+       encoding will only succeeed if the lat/lon is located in the territory.
+
+    mapcode [-g | --generate] <nrPoints> [<seed>]
+
+       Create a test set of a number of uniformly distributed lat/lon pairs,
+       3D x/y/z points and their Mapcodes). The output format is:
+           <nr> <lat> <lon> <x> <y> <z>
+           <territory> <mapcode>            (repeated 'nr' rtimes)
+           <1 empty line>
+
+       The points will be uniformly distributed over the 3D surface of the Earth
+       rather than using uniformly distributed lat/lon values.
+       Ranges:
+           nr > 1    lat = -90..90    lon = -180..180    x,y,z = -1..1
