+    General purpose importer for fileset entities. Simply fileset schema JSON
+    and inserts.
+
+    By default requires release_ids to be non-empty, and will check each
+    release_id to see if a fileset is already associated; if so, skips the
+    import. This behavior may change in the future, and can be disabled.
