+    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.
