+name: Changed Go modules
+description: |
+  Lists the Go modules a run should check, for a matrix of per-module jobs.
+
+  Every module is listed on a push, on a run with no changeset, and when any file under .github
+  changes. Otherwise a module is listed when any file in its directory changed, Go or not, since
+  embedded files are built in too. A file belongs to the deepest module containing it, and an
+  example module counts as its parent (see script/go-modules.sh).
+
+  Expects a checkout with full history.
