Hi Gerd, Please find an updated patch that I think captures the way the option works. I've tried to rewrite it as what it does rather than how it is implemented. I've also included an update to the top level help that removes the link to the OSM wiki as a provider of further information (it doesn't provide any) and adds a link to the geofabrik website as a source for input data. Let me know if you think the change still doesn't quite represent what happens. By the way, I'm not sure it is particularly logical to only remove words from the end of the label. There is also an error in the mkgmap home page, but the source doesn't seem to be included in the mkgmap distribution so I can't send a patch. The last sentence ends "and copy it to the cards in the Garmin directory" and I think it should say "and copy it to the card's /Garmin directory".

I fear the original text was really wrong. Your suggestion is better but it still doesn't catch the case that all(!) words might be removed. Assume option --mdr7-del=PTH,TRK,UNP,PAV and label is "PTH UNP" or just "PTH" In both cases the processing of --mdr7-del would end up in an empty label and thus nothing is added to MDR7 section. With a label "SCHILLERSTRASSE UNP" the part " UNP" is removed. With a label "UNP SCHILLERSTRASSE" nothing is removed. The code actually splits the label at every blank (space) into an array of words. Then it removes from right to left if the last word appears in the list. A label that doesn't contain a blank is an array with one element. I have no idea how well this works with languages that are read from right to left, but that's a different story. Maybe you find better wording?
