yes, good idea to use a symlink. That is a better solution.
I suggest we move the OSM data to the data/gisdata/ directory rather 
than data/osm directory, so that we keep all common data in the one

While you always have good programming tips when you review, I'm 
comfortable enough with my programming skills that your review is 
optional. I'm just making sure I'm not stepping on your toes by 
suggesting you review what I've done.
