--- Replace versioningit with setuptools-scm, lower the setuptools
--- requirement to the version available in the FreeBSD ports tree, pin the
--- version statically, and exclude the top-level examples directory from
--- package discovery. The sdist has no git history, so dynamic versioning via
--- setuptools-scm falls back to an incorrect 0.1.0rc0, and examples/ otherwise
--- installs a conflicting site-packages/examples/ directory.
+-- Fix setuptools/PEP 621 compatibility on FreeBSD by relaxing the build
+-- backend requirements and using the table form for project.license. The
+-- upstream sdist uses a bare string and a setuptools floor newer than the
+-- version available in the ports tree.
