+Fiona is designed to be simple and dependable.  It focuses on reading
+and writing data in standard Python IO style and relies upon familiar
+Python types and protocols such as files, dictionaries, mappings, and
+iterators instead of classes specific to OGR.  Fiona can read and write
+real-world data using multi-layered GIS formats and zipped virtual file
+systems and integrates readily with other Python GIS packages such as
+pyproj, Rtree, and Shapely.")
