Sometime ago I wrote a perl script as a learning exercise that also
returned something useful to me - I'm still using it for my backup
needs. I called it dupit, because it's just a minimal front end to
duplicity. It's purpose is to create duplicity "profiles", aka a bunch
of strings that are arguments to duplicity, to be run by a cron job that
is configured on the setup fase of the profile.

To setup a profile, just run $ dupit -s $profilename. You will be asked
for the arguments for duplicity on sensible, verbose, terms.

Then "dupit -b $profilename" to backup and "dupit -l $profilename" to
list settings. "$dupit -h" or "$man help" for a longer description of
its capabilities and limitations compared to duplicity.
