+If it's an OAR, or other sim defining format, or a model format, then create .omg files, stuff into .cache/converted/ or inventory/converted.
+  Or should conversion be a separate tool?
+    The problem is that we need to link back to the original archive, or carry other info like the archive type with us from here.
+    So might as well start the process by creating basic .omg files, with the info we have here, before we lose that info.
