# Script to check output of some translated messages
#
# This should be useful for translators to check that the translated strings
# look good. This doesn't make xz print all possible strings, but it should
# cover most of the cases where mistakes can easily happen.
#
# Give the path and filename of the xz executable as an argument. If no
# arguments are given, this script uses ../src/xz/xz (relative to the
# location of this script).
#
# You may want to pipe the output of this script to less -S to view the
# tables printed by xz --list on a 80-column terminal. On the other hand,
# viewing the other messages may be better without -S.
