[mkgmap-dev] Suggestion: Add option to remove area after convert to poi

Hi, The --add-pois-to-areas option is very useful to create maps. However, in certain cases I wish to have a clear poi file in addition to the garmin NT navigation file, so that can use the feature like speed limit and "garmin real directions". Thus an option such like --poi-only that removes all non-poi data at end of the process would be great. Thanks, Ke
