|
|
# ==== Notes
|
|
# options parameter must include values for :aws_access_key_id and
|
|
# :aws_secret_access_key in order to create a connection
|
|
#
|
|
# ==== Examples
|
|
# sdb = SimpleDB.new(
|
|
# :aws_access_key_id => your_aws_access_key_id,
|
|
# :aws_secret_access_key => your_aws_secret_access_key
|
|
# )
|
|
#
|
|
# ==== Parameters
|
|
# * options<~Hash> - config arguments for connection. Defaults to {}.
|
|
#
|
|
# ==== Returns
|
|
# * EC2 object with connection to aws.
