Bear in mind that before this merge step, I've already built the various 
tiles .img files and set the description, area-name, family-name 
correctly (and verified this by making a gmapsupp.img for each layer 
individually).  So it seems unnecessary to have to do it again at the 
point of merging the layers into one final file.

But anyhow, if I were to follow your suggestion I would need to supply 
multiple .args files - one for each layer.  But if I try the following 
it doesn't work (I end up with a single layer, the last one on the 
command line):

java -jar mkgmap.jar --gmapsupp
  -c contours.args contours.TYP
  -c base.args base.TYP
  -c routing.args

I need multiple .args files to control things like:
draw-priority
transparent
family-name etc

for each layer.

What am I missing?!
