 The created bottle files (`.bottle.tar.gz` and `.json`)  must be collected. The naming should be identical, i.e. use the same revision of 0 (if not explicitly intended).   `bottle.<revision>.tar.gz`. For revision 0 `<revision>.` is empty. If a previous bottle of the same version exist the name will include a new revision. For beta releases it might be possible to remove the revision if necessary from the `tar.gz` and the `json`.
