dnl GP_GETTEXT_HACK
dnl
dnl gettext hack, originally designed for libexif, libgphoto2, and Co.
dnl This creates a po/Makevars file with adequate values if the
dnl po/Makevars.template is present.
dnl
dnl Example usage:
dnl    GP_GETTEXT_HACK([${PACKAGE_TARNAME}-${LIBFOO_CURRENT}],
dnl                    [Copyright Holder],
dnl                    [foo-translation@example.org])
dnl    ALL_LINGUAS="de es fr"
dnl    AM_GNU_GETTEXT_VERSION([0.14.1])
dnl    AM_GNU_GETTEXT([external])
dnl    AM_PO_SUBDIRS()
dnl    AM_ICONV()
dnl    GP_GETTEXT_FLAGS
dnl
dnl You can leave out the GP_GETTEXT_HACK parameters if you want to,
dnl GP_GETTEXT_HACK will try fall back to sensible values in that case:
