+
+This module has been deprecated by the Gtk-Perl project.  This means that the
+module will no longer be updated with security patches, bug fixes, or when
+changes are made in the Perl ABI.  The Git repo for this module has been
+archived (made read-only), it will no longer possible to submit new commits to
+it.  You are more than welcome to ask about this module on the Gtk-Perl
+mailing list, but our priorities going forward will be maintaining Gtk-Perl
+modules that are supported and maintained upstream; this module is neither.
+
+Since this module is licensed under the LGPL v2.1, you may also fork this
+module, if you wish, but you will need to use a different name for it on CPAN,
+and the Gtk-Perl team requests that you use your own resources (mailing list,
+Git repos, bug trackers, etc.) to maintain your fork going forward.
