+;;; Modules (libraries) which are part of the Golang project but outside the
+;;; main Golang tree, see <https://pkg.go.dev/golang.org/x>
+;;;
+;;; Since they are bound to be relied on by many, their dependencies should be
+;;; kept minimal, and this module should not depend on other modules
+;;; containing Golang packages.
+;;;
+;;; Please: Try to add new module packages in alphabetic order.
