AWScala enables Scala developers to easily work with Amazon Web Services in the Scala way.
Though AWScala objects basically extend AWS SDK for Java APIs, you can use them with less stress on Scala REPL or sbt console.

Tests require aws credentials with Administrator permissions:
export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=yyy
The DynamoDB tests also require a locally running instance of DynamoDB.
An install script is provided as bin/installDynamoDbLocal.
A launch script is provided as bin/runDynamoDbLocal.
See http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Tools.DynamoDBLocal.html for more info.
To run the tests, just type sbt test.
