Usage()
{

	cat <<EOF
find-lang - generate list of language specific files for inclusion
            in an rpm spec %files section.

find-lang is free software, covered by the GNU General Public License.
find-lang comes with ABSOLUTELY NO WARRANTY, see license for details.

Usage: $PROG options PACKAGE_NAME

Valid options are:
--without-mo        do not look for locales files;
--with-man          look for man pages;
--with-gnome        look for GNOME help and omf files;
--append            do not truncate output file before writing;
--output=FILENAME   filename where to write output, by default PACKAGE_NAME.lang;
--topdir=TOPDIR     the top of the tree containing the files to be processed,
                    by default \$RPM_BUILD_ROOT.

Top directory gets sed'd out of the output list.
PACKAGE_NAME is usually the %{name} of the package. This should also be
the basename of the .mo files.
