Stop Rewrite Code of LiSP

For days, I plans to read code of _LiSP_, and rewrite it in CommonLisp, but it seems I failed. I do not have a copy of that book, just download a copy of the code accompany with the book from Internet. Util now, I have rewrote code of chapter 4, an interpreter written using closures and in continuation passing style, but I have not test it.

For there is little comment in the code, and I do not have the text, it is very hard for me to grasp ideas behind the code, take chapter 4 as an example. So I decide to stop right now. Maybe I will make it through later at some time.
