DESCRIPTION
    This module provides a Perlish interface to Amazon S3. From the
    developer blurb: "Amazon S3 is storage for the Internet. It is designed
    to make web-scale computing easier for developers. Amazon S3 provides a
    simple web services interface that can be used to store and retrieve any
    amount of data, at any time, from anywhere on the web. It gives any
    developer access to the same highly scalable, reliable, fast,
    inexpensive data storage infrastructure that Amazon uses to run its own
    global network of web sites. The service aims to maximize benefits of
    scale and to pass those benefits on to developers".

    To find out more about S3, please visit: http://s3.amazonaws.com/

    To use this module you will need to sign up to Amazon Web Services and
    provide an "Access Key ID" and " Secret Access Key". If you use this
    module, you will incurr costs as specified by Amazon. Please check the
    costs. If you use this module with your Access Key ID and Secret Access
    Key you must be responsible for these costs.

    I highly recommend reading all about S3, but in a nutshell data is
    stored in values. Values are referenced by keys, and keys are stored in
    buckets. Bucket names are global.

    Some features, such as ACLs, are not yet implemented. Patches welcome!

METHODS
  new
    Create a new S3 client object. Takes some arguments:

    aws_access_key_id
        Use your Access Key ID as the value of the AWSAccessKeyId parameter
        in requests you send to Amazon Web Services (when required). Your
        Access Key ID identifies you as the party responsible for the
        request.

    aws_secret_access_key
        Since your Access Key ID is not encrypted in requests to AWS, it
        could be discovered and used by anyone. Services that are not free
        require you to provide additional information, a request signature,
        to verify that a request containing your unique Access Key ID could
        only have come from you.

        DO NOT INCLUDE THIS IN SCRIPTS OR APPLICATIONS YOU DISTRIBUTE.
        YOU'LL BE SORRY

    secure
        Set this to 1 if you want to use SSL-encrypted connections when
        talking to S3. Defaults to 0.

    timeout
        How many seconds should your script wait before bailing on a request
        to S3? Defaults to 30.

  buckets
    Returns undef on error, else hashref of results

  add_bucket
    Takes a hashref:

    bucket
        The name of the bucket you want to add

    Returns 0 on failure, Net::Amazon::S3::Bucket object on success

  bucket BUCKET
    Takes a scalar argument, the name of the bucket you're creating

    Returns an (unverified) bucket object from an account. Does no network
    access.

  delete_bucket
    Takes either a Net::Amazon::S3::Bucket object or a hashref containing

    bucket
        The name of the bucket to remove

    Returns false (and fails) if the bucket isn't empty.

    Returns true if the bucket is successfully deleted.

  list_bucket
    List all keys in this bucket.

    Takes a hashref containing a single key:

    bucket
        The name of the bucket you want to list keys on

    Returns undef on error and a hashref of data on success:

    The hashref looks like this:

      {
            bucket       => $bucket_name,
            prefix       => $bucket_prefix, 
            marker       => $bucket_marker,
            max_keys     => $bucket_max_keys,
            is_truncated => $bucket_is_truncated_boolean
            keys          => [$key1,$key2,...]
       }
        
    Each key looks like this:

         {
            key           => $key,
            last_modified => $last_mod_date,
            etag          => $etag,
            size          => $size, # Bytes?
            storage_class => $storage_class # Doc?
            owner_id      => $owner_id,
            owner_displayname => $owner_name
        }

  add_key
    DEPRECATED. DO NOT USE

  get_key
    DEPRECATED. DO NOT USE

  head_key
    DEPRECATED. DO NOT USE

  delete_key
    DEPRECATED. DO NOT USE

TESTING
    Testing S3 is a tricky thing. Amazon wants to charge you a bit of money
    each time you use their service. And yes, testing counts as using.
    Because of this, the application's test suite skips anything approaching
    a real test unless you set these three environment variables:

    AMAZON_S3_EXPENSIVE_TESTS
        Doesn't matter what you set it to. Just has to be set

    AWS_ACCESS_KEY_ID
        Your AWS access key

    AWS_ACCESS_KEY_SECRET
        Your AWS sekkr1t passkey. Be forewarned that setting this
        environment variable on a shared system might leak that information
        to another user. Be careful.
