      ssh-pkcs11-helper is not intended to be invoked by the user, but from
      ssh-agent(1).
 
+     A single option is supported:

+     -v      Verbose mode.  Causes ssh-pkcs11-helper to print debugging
+             messages about its progress.  This is helpful in debugging

+             ssh-pkcs11-helper when it has itself been placed in debug mode.
