+ * The following is loosely based on an article by Simon Tatham:
+ * <http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html>.
+ * However, many improvements and tweaks have been made, in particular
+ * by taking advantage of C++ features not available in C.
+ *
+ * Why is this code here? Well, the Tinsel engine apparently used
+ * setjmp/longjmp based coroutines as a core tool from the start, and
+ * so they are deeply ingrained into the whole code base. When we
+ * started to get Tinsel ready for ScummVM, we had to deal with that.
+ * It soon got clear that we could not simply rewrite the code to work
+ * without some form of coroutines. While possible in principle, it
+ * would have meant a major restructuring of the entire code base, a
+ * rather daunting task. Also, it would have very likely introduced
+ * tons of regressons.
+ *
+ * So instead of getting rid of the coroutines, we chose to implement
+ * them in an alternate way, using Simon Tatham's trick as described
+ * above. While the trick is dirty, the result seems to be clear enough,
+ * we hope; plus, it allowed us to stay relatively close to the
+ * original structure of the code, which made it easier to avoid
+ * regressions, and will be helpful in the future when comparing things
+ * against the original code base.
