// *** NOTE TO THE READER ***
//
// Maybe you have just opened this file in the hope to learn more about the
// Yosys API. Let me congratulate you on this great decision! ;)
//
// If you want to know how the design is represented by Yosys in the memory,
// you should read "kernel/rtlil.h".
//
// If you want to know how to register a command with Yosys, you could read
// "kernel/register.h", but it would be easier to just look at a simple
// example instead. A simple one would be "passes/cmds/log.cc".
//
// This header is very boring. It just defines some general things that
// belong nowhere else and includes the interesting headers.
//
// Find more information in the "CodingReadme" file.
