Description:

mapset.py -     if you want to build more than one mapset, as example dach and
                germany.

                mapset.py -h shows a help

pygmap3.py -    the main script, start it without any option to create map
                for Germany with the default style of mkgmap

                you need a poly file of the region, 
                if you want to build yourchoice of region, store this file 
                in the subfolder poly.
                search for osm2poly and poly2osm in the web, if you want to
                create a poly file from scratch.

                you can also use rawdata files like germany-latest.osm.pbf from
                https://download.geofabrik.de
                store this file in a subfolder of the work dir named pbf.
                the same is possible with o5m files, store these files in the
                subfolder o5m.
                files with names like germany or germany-latest.[pbf|o5m] can be used.
                to prevent large updates, download a poly for this region, too, and 
                store it in the folder poly.                i

                it is also possible to use a planet file to create the raw data, but
                this download is huge, in 2020 ~55 GB.
                extracting raw data from a planet is slow, so try to use smaller
                extracts

                all raw data from pbf files will be converted to o5m,
                stored, updated and used in future builds.

                if you want to create your maps with your own styles,
                you have to do some work:

                    add a folder named {your_map}_style and a textbased file
                    named {your_map}_typ.txt to the folder 'styles'

                you can also use our fork of the AIO, copy the complete
                repository to 'styles'

                pygmap3.py -h shows a help
                pygmap3.py -m basemap enable the build of our basemap style

planet_up.py -  download  a complete planet from openstreetmap.org or update it


all other *.py are helper for 'pygmap3.py', they must be in the same folder!
