Looks good. Although you should not use --force or --assume-clean,
you wouldn't have needed them, but they also don't make a difference
in the above command.

the united nations did a poll about food. the only question they asked
was: "could you please give your honest opinion about a solution for
the shortage of food in the rest of the world?" this poll failed
because:
  - in africa they didn't know what food was....
  - in eastern-europe they didn't know what honest was....
  - in western-europe they didn't know what shortage was...
  - in china they didn't know what opinion was...
  - in the middle-east they didn't know what solution was...
  - in south-america they didn't know what please was...
  - and in the usa they didn't know what "the rest of the world" was...
