note you can use g.proj to make cs2cs easy.

e.g., transform Lat/Lon WGS84 points to the current GRASS location's
projection:

IN_PROJ="+proj=longlat +towgs84=0.000,0.000,0.000"
OUT_PROJ="`g.proj -jf`"

cat input.txt | cs2cs -f %.7f $IN_PROJ +to $OUT_PROJ > output.txt


These few lines would be in GRASS already as a replacement for m.proj2
if I could figure out how to optionally pipe input to the script with a
bit better control than "read" gives and a good name for it (no more m.*
modules).
