=head1 delete-s3-bucket.pl

Deletes an entire S3 bucket.

This command removes a bucket from Amazon's S3 service. The login and
password for S3 must be set using the C<--access-key> and C<--secret-key>
flags, unless defaults have been set in the Virtualmin configuration.

The C<--bucket> flag must be given to specify the bucket to be removed. To
have files in the bucket removed as well, use the C<--recursive> flag.
