+The Guix Build Coordinator package contains a script to query an
+instance of the Guix Data Service for derivations to build, and then
+submit builds for those derivations to the coordinator.  The service
+type below assists in running this script.  This is an additional tool
+that may be useful when building derivations contained within an
+instance of the Guix Data Service.
