[mkgmap-dev] mkgmap doing excessive writing

I suggest the new option should be named /reuse=<comma separated list of files, wildcards enabled>. /exampel /reuse=40000001.img, 40005*.img. /If this option is used, then mkgmap should not overwrite the listed folders in the <name>gmap. Naturally mkgmap should writea new tdb, preview.img, mdr and idx. In most cases the /reuse folders /contains Contourlines or other static content. Thomas
