+Subject: [PATCH] pyproject.toml: declare license-files so the wheel ships
+ jack2's licence
+
+meson-python only auto-includes the file named in the legacy
+[project.license].file table (a single file, no glob); it does not
+implement the PEP 639 default LICEN[CS]E* glob that setuptools and
+scikit-build-core apply when license-files is absent. [tool.cibuildwheel
+.linux] before-all builds JACK2 1.9.22 from source and links libjack (LGPL
+v2.1+) into the extension - auditwheel then vendors libjack.so.0 into the
+wheel (only libasound.so.2 is excluded via --exclude) - so its licence has
+to travel with the wheel too.
+
+Switch project.license to the SPDX string form (dropping the now-redundant
+'License :: OSI Approved :: MIT License' classifier, which pyproject-
+metadata rejects alongside an SPDX expression) and add license-files
+listing both LICENSE.md and a new LICENSE.jack2. The before-all list gains
+one more step, copying jack2's own COPYING to the project root as
+LICENSE.jack2 right after 'waf install', so it exists before meson-python
+reads project metadata.
