Subject: * Allow archiver to save and load objects within other objects to
arbitrary levels * This currently has various bugs which are more to do with
the way its been hacked together than the feature itself (e.g. on save-oar,
ghost prims will appear of the saved contained items). These will be found
and eliminated in subsequent patches. * Not yet ready for use
