-- Route files staged under ``{py_purelib}/<name>-<version>.dist-info/...``
-  or ``{py_platlib}/<name>-<version>.dist-info/...`` into the wheel's
-  ``.dist-info/`` directory at pack time. This is the recommended mechanism
-  for placing PEP 770 SBOMs and other dist-info-bound metadata files in the
-  wheel, removing the need for post-build wheel surgery. Works with both
-  static ``install_data()`` and dynamic ``custom_target(install: true)``,
-  and with ``pure: false`` projects (which stage under ``{py_platlib}``)
-  as well as pure-Python packages. Requires no new meson API. The distinfo
-  directory name is compared canonically, so hyphens vs. underscores in the
-  user's ``meson.project_name()`` don't break routing. The existing
-  collision check surfaces overlaps between files routed here and PEP 639
-  ``license-files`` written by the metadata layer. Routing is enforced for
-  non-editable wheels; editable wheels do not include dist-info-bound files
-  (a known limitation).
+- Add support for including PEP 770 SBOMs and other dist-info-bound metadata
+  files in the wheel. Files installed to ``<name>-<version>.dist-info/<subdir>/``
+  under ``{py_purelib}`` or ``{py_platlib}`` are routed into the wheel's
+  ``.dist-info/<subdir>/`` at pack time.
