`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`
2. Execute your sync

```bash
# s3sync help
Sync files from <from> to <to>

Usage:
  s3sync <from> <to> [flags]
  s3sync [command]

Available Commands:
  version     Returns the current version of s3sync
  help        Help about any command

Flags:
  -d, --delete=false: Delete files on remote not existing on local
  -h, --help=false: help for s3sync
  -P, --public=false: Make files public when syncing to S3
