Improved duplicity handler: option to disable remote files cleaning, optionnal backups gpg signing, option to specify the gpg key to use, nicelevel & testconnect options, optionnal string to pass to ssh/scp e.g. to use a non-default identity file ; created an example.dup file ; config is now split in sections.
