[mkgmap-dev] Please test branch NET-no-NOD

Hi Gerd
split.list contains:
74210001: 2362592,-73088 to 2376288,-50304
Note feed in a lot of points (postcodes) into the splitter, but there
is nothing in the default style that will process them.
splitter command line is:
java -Xmx1540M -ea -jar ../splitter/splitter.jar --geonames
-file=../cities15000.zip --mapid=74210001 --split-file=split.list
../mapGB/british-isles-latest.osm.pbf postcode.so.osm.xml >splitter.log
2>&1
# significant lines in ../mkgmap.opt

link-pois-to-ways

remove-ovm-work-files
poi-address
verbose

add-boundary-nodes-at-admin-boundaries=0
Command line is:
java -Xmx1540M -ea -Dlog.config=../mkgmap_log.props -jar
../mkgmap.noNod/mkgmap.jar -c ../mkgmap.opts --no-style-file --x-check
-routing-island-len=700 --family-id=7421 --family-name=Hants -c
template.args ../mytyp.txt
I'm going to be out for the next few hours, but can do the log stuff
later if you need it.
