Also of possible interest is the link to the actual interpreter source code.

http://www.t3x.org/s9fes/index.html

Only problem is, you have to navigate your way through a maze to get to the actual code from there.

I wrote a quick hacked-up web crawler (in emacs lisp, of all things!) to solve it because I was too impatient to do it for real.

That's really cute, but since you've solved the maze, can you tell me what the copyright encumbrance on that code is? Is it open? (By which I mean, is it worth my while to write my own crawler?)

Here's the license, copied verbatim from his LICENSE file:

* Do whatever you want with this code. * If the code doesn't work, don't blame me.

Ah - thanks. A direct link: http://github.com/barak/scheme9 (I feel better now).

However, this version has little or nothing in common with the one on my homepage. And: S9fES (the interpreter) is in the public-domain.

[Vivtek]

Oh, I do like public domain.

I'm going to wrap it in a Perl module so the whole thing comes right down from CPAN, just like SQLite. This is exactly what I've been waiting for, for years.
