[turns out Debian's netcat isn't standard, it has a -q timeout flag]

$USER_PROJ is the projection parameters used by PROJ.4's cs2cs.
(i.e. everything after the +to)

That is the projection parameters for your current location.
You might look at g.projinfo for some ideas.

It's probably better to rewrite the script to use 5.3's m.proj2..


Watch this space, more code is on the way ...
