+      The Apple File System (APFS) is the copy-on-write filesystem currently
+      used on all Apple devices. This module provides a degree of experimental
+      support on Linux.
+      If you make use of the write support, expect data corruption.
+      Read-only support is somewhat more complete, with sealed volumes,
+      snapshots, and all the missing compression algorithms recently added.
+      Encryption is still not in the works though.
