THIS EXAMPLE ZIPS MULTIPLE FILES & USES GO(GOLANG) ECHO

One of the things that makes S3zippper standout, is its ability to run file compression as a background task. This makes it such a convenience for users that want to do this programmatically, and don’t have time to wait around while the tasks are being completed.
One such task would be a user that needs to sell MP3 song selections, or offer specific files for download to specific users regularly or dynamically. This can be a hard task if done manually.
Another nice feature is the ability to specify natural file paths like you would do on a personal computer(PC). All file paths start from the bucket name as the root source e.g. /bucket_name/path/to/file/or/folder.
