    (description
     "Threading Building Blocks (TBB) is a C++ runtime library that abstracts
the low-level threading details necessary for optimal multi-core performance.
It uses common C++ templates and coding style to eliminate tedious threading
implementation work.  It provides parallel loop constructs, asynchronous
tasks, synchronization primitives, atomic operations, and more.")
