+Gambit consists of two main programs: gsi, the Gambit Scheme interpreter,
+and gsc, the Gambit Scheme compiler.
+
+The interpreter contains the complete execution and debugging environment. The
+compiler is the interpreter extended with the capability of generating
+executable files. The compiler can produce standalone executables or compiled
+modules which can be loaded at run time. Interpreted code and compiled code
+can be freely mixed.
+
+Gambit-C is a version of the Gambit programming system in which the compiler
+generates portable C code. The main features of Gambit-C are:
+
+ * Conformance: The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme
+   standards and implements all optional features. Tail calls and first class
+   continuations conform to the Scheme semantics. The full numeric tower is
+   implemented, including: arbitrary precision integers (bignums), rationals,
+   inexact reals (floating point numbers), and complex numbers. Several
+   extensions to Scheme are provided, including: lightweight threads, a
+   foreign-function interface (FFI), and extended I/O capabilities (Unicode,
+   networking, subprocesses, ...).
+
+ * Portability: Because the system is mostly written in Scheme and the compiler
+   generates portable C code, it is easy to port the system as well as programs
+   compiled with it to any platform with a decent C or C++ compiler. There
+   is no reliance on a particular C compiler, although the system can
+   take advantage of some gcc-specific constructs. The C code generated
+   is oblivious to the endianness and word size of the target environment
+   (32 and 64 bit architectures are currently supported).
+
+ * Performance: The compiler includes several powerful program transformations
+   such as user procedure inlining, partial-evaluation, and
+   lambda-lifting. With appropriate declarations in the source code the
+   executable programs generated by the compiler run roughly as fast as
+   equivalent C programs. Programs containing no declarations are also
+   optimized without compromising the Scheme semantics by speculatively
+   inlining predefined procedures (see the benchmarks page for a comparison
+   with other Scheme implementations and other languages). Thanks to an
+   efficient implementation of continuations, the thread system is very
+   efficient and can support millions of concurrent threads.
+
+ * Reliability: Stable releases typically have very few bugs. Bug tracking is
+   done with bugzilla. Gambit-C has been used to develop large-scale real-world
+   software and services in academic and commercial settings.
