[OSM-dev] Simplifying ways

I use osmosis [1,2] with osmosis-simplifyways plugin [3,4]. I have
attached my scripts for instruction, do not "just use" them!
I've tried gpsbabel as well but do not remember the results.
(gpsbabel -i osm -f "${_src}" -x simplify,crosstrack,error=0.001k \
    -o osm,tag="normalized:yes",created_by= -F "${_tgt}")
