# This script is used to create the mo files for applications using
# the simple gettext implementation provided by libgpg-error. That
# gettext can only cope with utf-8 encoded mo files; thus we make this
# sure while creating the mo. A conversion is not done if the source
# file does not exist or if it is not newer than the mo file.
