// DESCRIPTION:

//   All the global variables that store the internal state.

//   Theoretically speaking, the internal state of the engine

//    should be found by looking at the variables collected

//    here, and every relevant module will have to include

//    this header file.

//   In practice, things are a bit messy.

//
