+     "SystemC is a C++ library for modeling concurrent systems, and the
+reference implementation of IEEE 1666-2011.  It provides a notion of timing as
+well as an event-driven simulations environment.  Due to its concurrent and
+sequential nature, SystemC allows the description and integration of complex
+hardware and software components.  To some extent, SystemC can be seen as
+a Hardware Description Language.  However, unlike VHDL or Verilog, SystemC
+provides sophisticated mechanisms that offer high abstraction levels on
+components interfaces.  This, in turn, facilitates the integration of systems
+using different abstraction levels.")
