I tried looking for relevant code in the GRASS 4.1 source but found
nothing that would perform coordinate conversions in this manner.
I ended up having to use another software product (Trimble's Pathfinder
Office) to re-export the data in the right datum.

The only programs I found in GRASS were m.ll2u and m.u2ll, but they
only converted UTM to Lat/Long or back again.

My GPS data had originally been exported as Lat/Long, but I needed it in
Australian Map Grid 93 or something, which is based on UTM.
