# USAGE: my_bucket_put FILE_1 [FILE_N...]
# Uploads $local_path_for_bucket/FILE_1 to my_bucket/FILE_1

# This script has very little configuration to keep it simple (and serve my limited needs).
# Create a pre-configured copy of this for all your buckets. Or add command line flags.
# 
# Change this to your bucket name
bucketname = "my_bucket"

# Change this to the directory where your bucket files are.
local_path_for_bucket = "/Users/foo/my_bucket"
