Usage

Batch delete files in S3 by listing content iteratively with a prefix.

$ s3rm --bucket-name ${BUCKET_NAME} --prefix ${PATH}

Batch delete tiles in S3 using a bbox in LV95:

$ s3rm --bucket-name ${BUCKET_NAME} --prefix /1.0.0/ch.swisstopo.fixpunkte-agnes/default/current/2056/* --bbox 2671000,1139000,2712250,1158500 --image-format png

You can always use the help function:

$ s3rm --help
usage: s3rm [-h] -b BUCKETNAME -p PREFIX [--profile PROFILENAME] [--bbox BBOX]
            [-n NBTHREADS] [-s CHUNKSIZE] [-i IMAGEFORMAT] [-lr LOWRES]
            [-hr HIGHRES] [-f]

Purpose:
    This script is intended for efficient and MASSIVE RECURSIVE
    DELETION of S3 'folders'. This mean that any resource matching with
