Manifest captures the actions a generator performs. Instantiate a manifest with an optional target object, hammer it with actions, then replay or rewind on the object of your choice.

Example:

manifest = Manifest.new { |m|
  m.make_directory '/foo'
  m.create_file '/foo/bar.txt'
}
manifest.replay(creator)
manifest.rewind(destroyer)
