Another idea: adapt the book to ePub format extended with Javascript
(apparently latest ePub draft has such scripting capabilities) and use
js_of_ocaml tool to embed an OCaml toplevel inside the book: read the
examples, execute examples, play with the examples! Wouldn't it be
nice? ;-)

If you have an interest in doing this, please join the ocamlweb project [1]. One of the features we'd like to support is good community generated documentation, and this is exactly the kind of technology I'd like to see implemented.

Wouldn't it be the non Free license, I would even start from the PDF. :-(

Unless the original authors gave permission to use it under a different license. This is very likely if we just ask.
