  21 // *** NOTE TO THE READER ***
  22 //
  23 // Maybe you have just opened this file in the hope to learn more about the
  24 // Yosys API. Let me congratulate you on this great decision!  ;)
  25 //
  26 // If you want to know how the design is represented by Yosys in the memory,
  27 // you should read "kernel/rtlil.h".
  28 //
  29 // If you want to know how to register a command with Yosys, you could read
  30 // "kernel/register.h", but it would be easier to just look at a simple
  31 // example instead. A simple one would be "passes/cmds/log.cc".
  32 //
  33 // This header is very boring. It just defines some general things that
  34 // belong nowhere else and includes the interesting headers.
  35 //
  36 // Find more information in the "CodingReadme" file.
