+Subject: [PATCH] Ship the licences of the libraries bundled in the wheels
+
+The Linux and Windows wheels bundle the shared libraries graphviz links --
+cairo, pango, fontconfig, freetype, harfbuzz, fribidi, libthai, libdatrie,
+graphite2, gd, libpng, libjpeg, libtiff, libwebp, libxcb and others. Several
+are LGPL and the rest are MIT/BSD-style; all of them require their licence
+text or copyright notice to travel with a binary redistribution. The wheels
+ship only pygraphviz's own LICENSE and LICENSE.graphviz.
+
+`license-files` is an explicit list, so setuptools' default LICEN[CS]E* glob
+is off and a licence file dropped beside LICENSE is ignored. Widen the second
+entry to LICENSE.* so the build can stage one file per bundled library --
+LICENSE.graphviz keeps matching, so nothing is lost.
+
+Upstream-Status: To upstream [same gap affects upstream's own manylinux and Windows wheels; not yet submitted to pygraphviz/pygraphviz]
