-Manual Procedure
-=
-
-Prep 
-== 
- Download updated maps: http://download.geofabrik.de/north-america.html and http://download.geofabrik.de/north-america/canada.html  
- Pull latest osmosis from http://wiki.openstreetmap.org/wiki/Osmosis 
- Pull latest mapsforge for osmosis from https://github.com/mapsforge/mapsforge/blob/master/docs/Downloads.md 
- 
-Process maps for device 
-== 
- Setup osmosis in a directory (unzip release -- ZIPBOMB ALERT!!!!) 
- Create plugins directory under osmosis 
- Move mapsforge release jar to osmosis/lib/default/ 
- Decompress maps (if they were previously compressed) 
- ./osmosis bin/osmosis --rb file=../maps/a_map.osm.pbf --mapfile-writer file=../maps/a_map.map 
-  * If you run out of heap space add JAVACMD_OPTIONS="-Xmx16g" to the start of the line 
-  * If increasing the heap doesn't work, append type=hd to end of command 
-  * You can merge maps using --merge passed to osmosis (before --mapfile-writer) using n-1 instances of --merge where n is the number of --rb or --rx options passed 
-
