| # Concurrency Utilities | Documentation Contents

> The Concurrency Utilities packages provide a powerful, extensible framework of high-performance threading utilities such as thread pools and blocking queues. This package frees the programmer from the need to craft these utilities by hand, in much the same manner the Collections Framework did for data structures. Additionally, these packages provide low-level primitives for advanced concurrent programming.
