[OSM-dev] wishlist: gpx merging tool

I want a tool which will take two or more GPX files (say, from two GPS
units in a car - one at the front, one at the back) and will merge them
with simple rules

1) If there's only one point for a timestamp use that
2) If there's more than one then average the position

and spit out a 3rd, averaged, GPX.

A poor mans differential GPS perhaps, but also I've seen a lot of
dropout from putting a GPS on a car dashboard and figure that putting
one at the back too (which will see a different set of satellites) might

have fun,
