The goal of this module is to offer a simple queue system using the underlying
file system for storage, security and to prevent race conditions via atomic
operations. It focuses on simplicity, robustness and scalability.
This module allows multiple concurrent readers and writers to interact with
the same queue.
A Perl implementation (Directory::Queue) and a Python implementation (dirq)
of the same algorithm are available so readers and writers can be written in
different programming languages.
