+DESCRIPTION
+    This is a stop-gap solution to identify parent inheritance of container
+    images until the container release automation[0] is in place and we have
+    fully automated rebuilds[1] in OSBS.
+    This information should be used such that the images can be rebuilt and
+    released in the appropriate order using flr-koji.
