" Language Information
"
"		Cynpp (Cyn++) is a macro language to ease coding in Cynlib.
"		Cynlib is a library of C++ classes to allow hardware
"		modelling in C++. Combined with a simulation kernel,
"		the compiled and linked executable forms a hardware
"		simulation of the described design.
"
"		Cyn++ is designed to be HDL-like.
