    """OPARI2 is a source-to-source instrumentation tool for OpenMP and 
       hybrid codes. It surrounds OpenMP directives and runtime library 
       calls with calls to the POMP2 measurement interface.
       OPARI2 will provide you with a new initialization method that allows 
       for multi-directory and parallel builds as well as the usage of 
       pre-instrumented libraries. Furthermore, an efficient way of 
       tracking parent-child relationships was added. Additionally, we 
       extended OPARI2 to support instrumentation of OpenMP 3.0 
       tied tasks. """
