+Subject: [PATCH] ship the MIT LICENSE in the wheel's dist-info
+
+setup.py declares `license = "MIT"` but never lists a `license_files`
+glob, and there is no pyproject.toml for setuptools' PEP 639
+auto-detection to fall back to. As a result every wheel upstream
+publishes (verified against the real
+edlib-1.3.9.post1-cp312-cp312-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
+from PyPI) carries no LICENSE file at all.
+
+Declaring `license_files = ["LICENSE"]` makes setuptools copy the
+repository's root LICENSE into dist-info/licenses/LICENSE. The build
+also copies that file into bindings/python/ first (see
+build-edlib.yml), since setup.py's own directory is the wheel-build
+context and the license otherwise lives two directories up.
+
+Upstream-Status: To upstream [not yet submitted; no fork of Martinsos/edlib to push from]
