# Amazon's S3 file hosting service is a scalable, easy place to store files for
# distribution. You can find out more about it at http://aws.amazon.com/s3
# There are a few S3-specific options for has_attached_file:
# * +s3_credentials+: Takes a path, a File, or a Hash. The path (or File) must point
# to a YAML file containing the +access_key_id+ and +secret_access_key+ that Amazon
# gives you. You can 'environment-space' this just like you do to your
# database.yml file, so different environments can use different accounts:
# development:
# access_key_id: 123...
# secret_access_key: 123...
# test:
# access_key_id: abc...
# secret_access_key: abc...
# production:
# access_key_id: 456...
# secret_access_key: 456...
# This is not required, however, and the file may simply look like this:
# access_key_id: 456...
# secret_access_key: 456...
# In which case, those access keys will be used in all environments.
# * +s3_permissions+: This is a String that should be one of the "canned" access
# policies that S3 provides (more information can be found here:
# http://docs.amazonwebservices.com/AmazonS3/2006-03-01/RESTAccessPolicy.html#RESTCannedAccessPolicies)
# The default for Paperclip is "public-read".
# * +bucket+: This is the name of the S3 bucket that will store your files. Remember
# that the bucket must be unique across all of Amazon S3. If the bucket does not exist
# Paperclip will attempt to create it. The bucket name will not be interpolated.
# * +path+: This is the key under the bucket in which the file will be stored. The
# URL will be constructed from the bucket and the path. This is what you will want
# to interpolate. Keys should be unique, like filenames, and despite the fact that
# S3 (strictly speaking) does not support directories, you can still use a / to
# separate parts of your file name.
