+Synopsis
+^^^^^^^^
+
+``kotlin MakeWaypointsKt`` [``-latfirst``] *file*
 
+Prompt for long, lat (or, with ``-latfirst``, lat, long) pairs and names and
+create a file containing the specified waypoints. Coordinates are expected to
+be two comma-separated floating-point numbers, with negative values indicating
+locations in the southern or western hemispheres (i.e. the standard way of
+representing coordinates in computer storage).
+
+Basic sanity checks are performed on the coordinates entered.
+
+Notes
+^^^^^
+
+This program is in Kotlin, despite my starting this project in Python, because
+the JVM has a much more concise and simple way (i.e. ``XMLStreamWriter``) for
+producing XML output.
+
+Longitude, not latitude, is first by default because that is the way QGIS
+exports coordinates.
