# Python program to extract country-specific SOTA peaks from "summitslist.csv"
# and write out an OSM file, "sotapoi_XX.osm", where XX is the region that
# was specified on the command line.  This .osm file can be processed by
# OsmAnd Map Creator to produce an .obf file for use with OsmAnd, showing
# SOTA peaks as POIs.
