+                    Enables "backsigs" support.  This is a currently
+                   experimental solution to a subtle OpenPGP protocol
+                   problem involving signing subkeys.  It is
+                   specified in the 2440bis drafts that will become
+                   the new OpenPGP standard, but is not finalized yet
+                   and has not had interoperability testing.  Use at
+                   your own risk.
