# ============================================================
# Will upload local source folder to the target S3 bucket.
# Please refer to script documentation for ways to configure.
# ============================================================
# This script REQUIRES AWS Tools for Windows PowerShell
# installed on default location, or specify Import-Module.
# Official download link: https://aws.amazon.com/powershell/
# ============================================================
# This is main part of the script, not really much to do here.
# To configure it, edit the configuration file: s3-upload.conf
