+	  Catch2 is mainly a unit testing framework for C++, but it
+	  also provides basic micro-benchmarking features, and simple
+	  BDD macros.
+
+	  Catch2's main advantage is that using it is both simple and
+	  natural. Tests autoregister themselves and do not have to
+	  be named with valid identifiers, assertions look like
+	  normal C++ code, and sections provide a nice way to share
+	  set-up and tear-down code in tests.
+
+	  This package allows running testsuites on the target which
+	  might be advantageous in certain cases.
