     "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.")

Programming, with a state of the art macro and module system on top of the Gambit
runtime.  The macro system is based on quote-syntax, and provides the full meta-syntactic
tower with a native implementation of syntax-case.  It also provides a full-blown module
system, similar to PLT Scheme's (sorry, Racket) modules.  The main difference from Racket
is that Gerbil modules are single instantiation, supporting high performance ahead of
time compilation and compiled macros.")
