Yes, just a different way of saying one's lat/long, it seems.

OK, List, what about it.  The main thing that spurred me on was that
proj wouldn't set an arbitrary limit of 6 characters, e.g. I live in
PL04KE, when outputting, like so many programs do, e.g. qgrid (which
is up for adoption) on debian.

Naturally, I don't have any burning need in mind, other than adding
another method to make sure the Martians can find me to
