# It is an example that handles S3 buckets on AWS.
# It uses Resource API (high-level) of Boto3.
# Move an object from a S3 bucket to another S3 bucket.
# You must provide 3 parameters:
# SOURCE_BUCKET      = Source bucket name
# SOURCE_OBJECT      = Source file name
# DESTINATION_BUCKET = Destination bucket name
