-OSMux - A query multiplexer for the Overpass OpenStreetMap-API
-
-Version 2011-10-22
-
-(c) 2011 - Conrad Hoffmann <ch@bitfehler.net>
-
-This software is public domain and comes without warranty of any kind.
-
-This script splits queries for large areas into several smaller bounding boxes, sends them to them
-to the server and merges the results into a single file (the result for the original query).
-
-Additionally, ways are returned as nodes, so they can be displayed in map overlays. Actually, for
-a matching way the script returns the first node of the way - but with all the tags that were 
-originally attached to the way.
-
-Basic usage instructions available via the --help switch. 
-
-See http://code.bitfehler.net/osmux for more details.
