[Ulrike Uhlig]

This is an automated email from the git hooks/post-receive script.

u-guest pushed a commit to branch master
in repository libgsecuredelete.

commit ff74d51a5bb16f4813092db9c08b8f8da7dc2c28
Author: Colomban Wendling <ban at herbesfolles.org>
Date:   Thu Oct 1 19:13:10 2009 +0200

    Added a generic property for the security mode.
    
    Added SecureDeleteOperationMode, SecureDeleteOperation:mode
    SecureDeleteOperation.get_argument_for_mode() and
    SecureDeleteOperation.add_mode_argument().
    Only the last one is meant to be used by implementations, even if
    they can call SecureDeleteOperation.get_argument_for_mode().
