+    - core client: if an input file has <generated_locally/> set,
+        don't try to download it.
+        This allows apps to use "initialization" files
+        that are large and/or computationally expensive to generate.
+        The app generates the file once,
+        and it will be available (assuming <sticky/> is set)
+        for subsequent workunits.
