  NOTES ON INTERNALS
  ==========================
  - Many of `masque`'s classes make use of `__slots__` to make them faster / smaller.
-    Since `__slots__` doesn't play well with multiple inheritance, the `masque.utils.AutoSlots`
-    metaclass is used to auto-generate slots based on superclass type annotations.
- - File I/O submodules are imported by `masque.file` to avoid creating hard dependencies on
-    external file-format reader/writers
+    Since `__slots__` doesn't play well with multiple inheritance, often they are left
+    empty for superclasses and it is the subclass's responsibility to set them correctly.
