Usage: $0 TOP_DIR PACKAGE_NAME [prefix]

where TOP_DIR is
the top of the tree containing the files to be processed--should be
\$RPM_BUILD_ROOT usually. TOP_DIR gets sed'd out of the output list.
PACKAGE_NAME is the %{name} of the package. This should also be
the basename of the .mo files.  the output is written to
PACKAGE_NAME.lang unless \$3 is given in which case output is written
to \$3.
Additional options:
  --with-gnome		find GNOME help files
  --with-mate		find MATE help files
  --with-kde		find KDE help files
  --with-qt		find Qt translation files
  --with-html		find HTML files
  --with-man		find localized man pages
  --all-name		match all package/domain names
  --without-mo		do not find locale files
  --generate-subpackages move language files in one sub package per language
