# This is a rudementary queue service that uses file system instead of
# AWS::SQS or SimpleQueue. It addresses SimpleQueue's inability to be used
# by only one application instance while avoiding the cost of setting up AWS::SQS.
# This is ideal to be used in development mode between multiple applications.
