Usage()
{

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

Usage: $PROG options PACKAGE_NAME

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.

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;
  --with-kde                look for KDE help files;
  --custom-dir-script=FILE  look for directories using specified sed script;
  --custom-file-script=FILE look for files using specified sed script;
  --custom-link-script=FILE look for symlinks using specified sed script;
  --append                  do not truncate output file before writing;
  --output=FILENAME         filename where to write output,
                            PACKAGE_NAME.lang by default;
  --topdir=TOPDIR           the top of the tree containing the files to be
                            processed, \$RPM_BUILD_ROOT by default;
  --version                 print program version and exit;
  --help                    show this text and exit.
