doing的终极地狱完整版。可以说doing的这个版本在ES2架构中算首屈一指的，虽然他说自己的作品很粗糙，但在多年来的国内MUD界来说，其严谨细致的思路及程序写法是绝对可以值得借鉴学习。可惜doing曾经说过，不太有可能再写文字MUD，如果可能再写也不会做现有hell架构的MUD。但这个版本足以是我们受益非浅了。(doing the ultimate hell full version. You can say that doing this version ES2 architecture considered second to none, although he says his work is very rough, but in the domestic sector has a MUD, its strict and meticulous thinking and program wording is definitely worth learning to learn. Unfortunately, doing once said, is not possible to write a text MUD, if possible, do not write it hell existing architecture MUD. But this version is that we greatly benefit from a sufficient.)
