+Osmium is a fast and flexible C++ library for working with OpenStreetMap data.
+
+The Osmium library has extensive support for all types of OSM entities:
+nodes, ways, relations, and changesets. It allows reading from and writing
+to OSM files in XML and PBF formats, including change files and full history
+files. Osmium can store OSM data in memory and on disk in various formats
+and using various indexes. Its easy to use handler interface allows you to
+quickly write data filtering and conversion functions. Osmium can create
+WKT, WKB, OGR, GEOS and GeoJSON geometries for easy conversion into many GIS
+formats and it can assemble multipolygons from ways and relations.
