# Awk script to extract translations for baseset descriptions
# from lang files for insertion into .obg/obs/obm files.
# If there is no translation, there is no output.
#
# The input file is scanned for the pattern
#  !! <ini-key> <STR_id>
#
# The lang files (passed as variable 'langfiles') are scanned for <STR_id> and
# the translations are added to the output file:
#  <ini-key>.<iso-code> = <translation>
#

# Simple insertion sort since not all AWKs have a sort implementation
