# Test of gettext facilities in the bash language.
# Assumes an fr_FR locale is installed.
# Assumes the following packages are installed: bash 2.0 or newer.

# This test fails on MacOS X 10.5 because its 'bash' command is built with
# an included intl directory without iconv support; hence it produces wrong
# output when accessing any .mo file not generated from a .po file in UTF-8
# encoding.
