 Unfortunately, data packs and resource packs aren't limited to neatly namespaced files and can contain extra files at the pack level and at the namespace level. Still, the `beet` library handles extra files as first-class citizens. In fact, `pack.mcmeta` and `pack.png` are both handled through this mechanism.
 
 ```py
-from beet import JsonFile
+from beet import Mcmeta
 
 pack = DataPack()
 
 pack.extra == {
-  "pack.mcmeta": JsonFile({"pack": {"description": "", "pack_format": 6}})
+  "pack.mcmeta": Mcmeta({'pack': {'min_format': (88, 0), 'max_format': (88, 0), 'description': ''}})
