+// 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.
