[mkgmap-dev] family-id & Co.

Hi! I haven't really understand what are the following mkgmap-options are for: -family-id -product-id -series-name -family-name -area-name -description -country-name -country-abbr -region-name -region-abbr I only knew that the map should have the same family-id (or was it the product-id?) as in the TYP-file. But what about the others? Which are really necessary? And where will these informations be displayed? Christian
