As I was searching a tiny scripting language for some project, I found tinyscheme. It is really venerable but old.

So I searched for a modern replacement in the existing one, browsing the very long list at http://community.schemewiki.org/?scheme-faq-standards#implementations.

And you what? I have not found one matching my criteria: r7rs compatible, only C, light, easy to add in C programs.

So I started to modify tiny-scheme to fit my requirement.

Before work, at noon rest, late in the evening, ... A long effort still not achieved.

I'd like to get a short time slot to present it.
