+Subject: [PATCH] package the licences of the embedded libev, libuv and c-ares
+
+Upstream-Status: To upstream [not yet submitted; the same gap exists in every gevent wheel on PyPI, so this needs a maintainer discussion rather than a drive-by PR]
+
+The wheels statically compile the bundled deps/libev, deps/libuv and
+deps/c-ares sources into gevent.libev.corecext, gevent.libev._corecffi,
+gevent.libuv._corecffi and gevent.resolver.cares. libev is BSD 2-clause
+(or GPL 2+), libuv and c-ares are MIT; all three require the copyright
+notice to travel with binary redistributions, but setup.py names only
+'LICENSE' in license_files, so the wheel ships gevent's own licence alone.
+
+The vendored c-ares tree carries no licence file at all -- the notice
+appears only in the per-file headers -- so restore LICENSE.md from the
+vendored release (c-ares 1.34.5).
+
+NOTICE is added for the same reason: it carries the PSF licence covering
+the stdlib test files copied under gevent/tests and the guv copyright of
+gevent/libuv/_corecffi_*.c, both of which do ship in the wheel.
