# SYNOPSIS
#
# This program reads the keyboard names file created by the make-kbd-info
# program and generates a PO file containing translations of the keyboard
# names into the language specified by the first command line argument.
# The translations are obtained from libDrakX.
#
# The keyboard names file (kbd-names.txt) is searched for in the directory
# containing this program. The PO file (${LANGUAGE}-kbd.po) is stored in
# the current working directory.
