+// Package announced contains tools for announcing API group factories. This is
+// distinct from registration (in the 'registered' package) in that it's safe
+// to announce every possible group linked in, but only groups requested at
+// runtime should be registered. This package contains both a registry, and
+// factory code (which was formerly copy-pasta in every install package).
