+Subject: [PATCH] pyproject: ship the bundled pkgconf licence
+
+The wheel ships the `pkgconf` executable built from the
+subprojects/pkgconf submodule, which is under the ISC licence. ISC
+requires its copyright and permission notice to appear in all copies,
+but `license-files = ['LICENSE']` only lists the wrapper's own MIT
+licence, and meson-python implements no default licence glob, so
+upstream's published wheels carry no pkgconf notice at all.
+
+List subprojects/pkgconf/COPYING as well; meson-python writes it to
+dist-info/licenses/subprojects/pkgconf/COPYING.
+
+Upstream-Status: To upstream [not submitted from this automated port run; needs a pull request against pypackaging-native/pkgconf-pypi]
