That doesn't want to work for me. I have the latest germany file and 
when I run that (with enableDateParsing set to no, otherwise it won't 
even start reading it), I get this error:

maarten at watcheye:~/osm$ osmosis/bin/osmosis --read-xml 
file=germany-latest.osm enableDateParsing=no --simplify-ways 
epsilonMeters=10 --write-xml file=germany-simplifyied.osm

Is this a case of not having it installed correctly, or is it something 
else?
