I can't remember either why this was set as default. Attached is a patch
that documents it.

Hi Carlos,
the tricky part here is that -tdbfile is enabled by default. I don't remember
why this was done, and I don't know why it is not documented, but you can use
--no-tdbfile to overwrite the default.

Betreff: [mkgmap-dev] Behavior of overview options
According to options file, --overview-mapname and --overview-mapnumber
parameters should only have an effect "If --tdbfile is enabled...", but
they seem to be always taken into account regardless of --tdbfile, as
can be checked with command: java -jar mkgmap.jar --gmapsupp
--overview-mapname=test --overview-mapnumber=0000001 test.osm
Additionally, overview files (osmmap.img, osmmap.tdb and ovm_XXX.img)
are created when only --gmapsupp is passed to mkgmap (no --tdb-file), as
in the command below:
java -jar mkgmap.jar --gmapsupp test.osm
I think if you just want to create a gmapsupp file, overview files are
not needed at all and they should not be created.
