This WordPress plugin is designed to remove assets from an Amazon S3 bucket when the source file has been removed from WordPress. It requires an S3 bucket that matches the layout of the wp-contents directory. Several constants are referenced in the code, so these must be set in wp-config.php. They are:

• AWS_REGION (e.g., 'us-east-1')
• AWS_ACCESS_KEY_ID (obtained from the AWS Console at IAM/Users/[your user]/Security Credentials)
• AWS_SECRET_ACCESS_KEY (as above)
• AWS_BUCKET (your bucket name)
• AWS_UPLOADS_PREFIX (the base path in the bucket)

The s3Delete plugin uses composer to provide both class autoloading and the AWS S3 SDK. These facilities are already part of this repository. Should it be necessary to update composer dependecies, delete the vendor directory and run composer install.
