s3cmd

I have a local directory that I would like to synchronize with an S3 bucket. I have two specific requirements:

If local file is the same as the remote, do not re-transfer it to the bucket.
If some files or directories exist in the bucket but do not exist on local, delete them. Basically the bucket should mirror the local copy and not vice-versa.

I looked into s3cmd sync command, but unfortunately requirement 2 is not fulfilled. If files exists in the bucket but not on local copy, they will be copied to the local instead of being deleted.
