I have complex requirements for configuration files.
I'm thinking about using Lisp as a configuration language.
I have written a longish proposal (7k) discussing my
idea. Some questions (3 of them) are at the end of the
story).

I have set up a webpage on angelfire because I think
7k is too much for usenet. And I can use <h3>,
<em> and <PRE>!

You don't need to reply here, email is welcome.

I have used XML, YAML, key=value, python and .ini-files
for configs in the past, but I think Lisp would serve *everybody*
better than those. Even if my proposal sucks at some
point, I think the overall direction is sound.
What do you think?

Kind regards
Tin

Aha! If that's all there is to it... Thanks! Amazing!
