=head1 delete-s3-file.pl

Deletes a single file from an S3 bucket.

This command removes a single file 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 the file is stored
in, and the C<--file> flag to choose the filename.
