+    (description
+     "TinyScheme is a light-weight Scheme interpreter that implements as large a
+subset of R5RS as was possible without getting very large and complicated.
+
+It's meant to be used as an embedded scripting interpreter for other programs.
+As such, it does not offer an Integrated Development Environment (@dfn{IDE}) or
+extensive toolkits, although it does sport a small (and optional) top-level
+loop.
+
+As an embedded interpreter, it allows multiple interpreter states to coexist in
+the same program, without any interference between them.  Foreign functions in C
+can be added and values can be defined in the Scheme environment.  Being quite a
+small program, it is easy to comprehend, get to grips with, and use.")
