description             Gambit-C is a fast Scheme implementation.
long_description        Gambit-C includes a Scheme interpreter and a Scheme \
                        compiler which can be used to build standalone \
                        executables. Because the compiler generates portable \
                        C code it is fairly easy to port to any platform \
                        with a decent C compiler. The thread system is very \
                        efficient and can support millions of concurrent \
                        processes. \
                        \
                        The Gambit-C system conforms to the R4RS, R5RS and \
                        IEEE Scheme standards. The full numeric tower is \
                        implemented, including: infinite precision integers \
                        (bignums), rationals, inexact reals (floating point \
                        numbers), and complex numbers.
