[mkgmap-dev] mkgmap:fast_road

Hi Gerd, Sorry If I missed the discussion about the tag "mkgmap: fast_road", but I did not see anything about this in the manual and neither searching the net. I became aware of this tag by downloading the mkgmap 3993 and analyzing the changes in the standard "line" and "relation" files. What is the pratical result/behavior of this tag in the routing? Thanks. Alexandre Loss
