This file contains information that might be useful.

When using the OSM_for_APRS application, folders for map projects are created
in the following directories:

* Windows XP - My Documents/osmmaps/mapnik directory
* Windows Vista - <User Name>/Documents/osmmaps/mapnik directory.

If you wish to use the sample OSM maps on the APRS-Go web site, and you 
will not be installing the OSM_for_APRS application, then you need to 
create the appropriate folders.  Copy the sample map file(s) into the mapnik
directory, and unzip the file.
