-/// DocumentClassBundle is a container for DocumentClass objects, so that
-/// they stay in memory for use by Insets, CutAndPaste, and the like, even
-/// when their associated Buffers are destroyed.
-/// FIXME Some sort of garbage collection or reference counting wouldn't
-/// be a bad idea here. It might be enough to check when a Buffer is closed
-/// (or makeDocumentClass is called) whether the old DocumentClass is in use
-/// anywhere.
-///
-/// This is a singleton class. Its sole instance is accessed via
-/// DocumentClassBundle::get().

+/// The only way to make a DocumentClass is to call this function.
+/// The shared_ptr is needed because DocumentClass objects can be kept
+/// in memory long after their associated Buffer is destroyed, mostly
