The gambc package includes a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. The thread system is very efficient and can support millions of concurrent processes.

The Gambit 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. Gambit supports a number of extensions to the standards.
