 # notes:
 #  - cs2cs expects "x y" data so be sure to send it "lon lat" not "lat lon"
 #  - if you send cs2cs a third data column, beware it might be treated as "z"
+# todo:
+#  - `cut` away x,y columns into a temp file, feed to cs2cs, then `paste`
+#    back to input file. see method in v.in.garmin.sh. that way additional
+#    numeric and string columns would survive the trip, and 3rd column would
+#    not be modified as z.
