+The first line of this file is machine-readable and is what the build gate
+reads to populate the licence shown on the companion's page. Every companion in
+this registry must carry one, because PRODUCT-SPEC E-3 requires a developer at a
+company to be able to see what they are allowed to use, and section 9 makes a
+100% licence-clean catalogue a launch metric.
