    "Statement" : [
      {
        "Effect":"Deny",
        "Sid":"1", 
        "Principal" : {
          "AWS":["1-22-333-4444","3-55-678-9100"]
        },
        "Action":["s3:*"],
        "Resource":"arn:aws:s3:::bucket/*",
      }
    ]
  }

See also L<GET Bucket Policy|http://docs.amazonwebservices.com/AmazonS3/latest/API/index.html?RESTBucketGETpolicy.html>

=head1 PUBLIC METHODS

=head2 files( page_size => $size, page_number => $number, [[marker => $marker,] pattern => qr/$pattern/ ] )

Returns a L<AWS::S3::FileIterator> object with the supplied arguments.

Use the L<AWS::S3::FileIterator> to page through your results.

=head2 file( $key )

Finds the file with that C<$key> and returns an L<AWS::S3::File> object for it.

=head2 delete_multi( \@keys )

Given an ArrayRef of the keys you want to delete, C<delete_multi> can only delete
up to 1000 keys at once.  Empty your buckets for deletion quickly like this:

  my $deleted = 0;
  my $bucket = $s->bucket( 'foobar' );
  my $iter = $bucket->files( page_size => 1000, page_number => 1 );
  while( my @files = $iter->next_page )
  {
    $bucket->delete_multi( map { $_->key } @files );
    $deleted += @files;
    # Reset to page 1:
    $iter->page_number( 1 );
    warn "Deleted $deleted files so far\n";
  }# end while()
  
  # NOW you can delete your bucket (if you want) because it's empty:
  $bucket->delete;
