-;; This file also provides `plstore-mode', a major mode for editing
-;; the PLSTORE format file.  Visit a non-existing file and put the
-;; following line:
-;;
-;; (("foo" :host "foo.example.org" :secret-user "user"))
-;;
-;; where the prefixing `:secret-' means the property (without
-;; `:secret-' prefix) is marked as secret.  Thus, when you save the
-;; buffer, the `:secret-user' property is encrypted as `:user'.
-;;
-;; You can toggle the view between encrypted form and the decrypted
-;; form with C-c C-c.
+;; Currently not supported but in the future plstore will provide a
+;; major mode to edit PLSTORE files.
