+Description: The C++ Standards Library for Concurrency and Parallelism 
+  HPX is a C++ Standards Library for Concurrency and Parallelism. It implements all of the corresponding facilities as defined by the C++ Standard. Additionally, in HPX we implement functionalities proposed as part of the ongoing C++ standardization process. We also extend the C++ Standard APIs to the distributed case.
