`s3sync` is a small utility to sync local directories from/to Amazon S3 without installing any dependencies. Just put the binary somewhere into your path and set three ENV variables and your're ready to sync.
## Features
- Static binary, no dependencies required
- Sync files only if required (judged by MD5 checksum)
- Optionally delete files at target
- Optionally make files public on sync (only if file needs sync)
- Sync local-to-s3, s3-to-local, local-to-local or s3-to-s3
## Usage
1. Set `AWS_ACCESS_KEY`, `AWS_SECRET_ACCESS_KEY` and `AWS_REGION`
