# 10/21/2017 - Updated for newer versions of `test`
#
# Script to combine GPS .loc files in the current directory into one file
# Works only for xml formatted .loc files 8 lines long.
#
#      j is going to be set for our first iteration in which we print out the
# header.  Subsequent iterations print the data lines stripped from each .loc
# file.  Then the trailing </loc> is printed before EOF.
