usage       'prune'
summary     'removes files not managed by nanoc from the output directory'
description <<-EOS
Find all files in the output directory that do not correspond to an item
managed by nanoc and remove them. Since this is a hazardous operation, an
additional --yes flag is needed as confirmation.

Also see the auto_prune site configuration option in config.yaml, which will
automatically prune after compilation.
