The book is almost ready (as always?). I estimate one more month to
finish it all. What is missing?

* A quick explanation about tail calls ;)
* A section about using coroutines for colaborative multithreading
* A section with a larger example of a C library (it is a simple
binding to expat)
* a revision

One problem with "selling" it now is that soon it will be out-dated by
the final version. Maybe I could track buyers so they could have free
updates?

Another question: how much would be a fair price for an eletronic book?
(and unfinished! But then you could be buying in advance the final
version...)

Another question: should I put the book free and ask for donations,
instead of selling it?

(BTW: those willing to pay a little to help Lua please do not forget
John's lottery.)
