 Change "block" to "unblock" to remove a bug from the list.  Closed
 bugs are not listed as blockers, so you do not need to explicitly
 unblock one that has been closed.  You may need to force an update of
 the tracking bug with ctrl-f5/shift-reload to see the latest version.
 
+If you use the debbugs package from GNU ELPA, you can apply the
+following form to see all bugs which block a given release:
