+At the moment it is a fairly direct port of Peter Micheaux's [Bootstrap
+Scheme](https://github.com/petermichaux/bootstrap-scheme) (as described in
+[this wonderful series of blog posts](http://peter.michaux.ca/articles/scheme-from-scratch-introduction))
+from C to forth, but I plan to go a bit beyond this by implementing some
+nice features like garbage collection, macros and a more complete numerical
+tower to bring it closer to [R5RS](http://www.schemers.org/Documents/Standards/R5RS/).
