SLIB is a Scheme library written by Aubrey Jaffer which uses only standard syntax and consequently works on many different Scheme implementations, such as Bigloo, Chez Scheme, Extension Language Kit 3. Scheme is a Multi-paradigm programming language. It is one of the two main dialects of Lisp and supports a number of programming paradigms but is A library is a collection of information sources resources and services and the structure in which it is housed it is organized for use and maintained by a public body an institution Aubrey Jaffer is a Mathematician who has written several Free software programs such as the SCM Scheme implementation which forms the core Bigloo is an implementation of the Scheme programming language developed at the French IT research institute INRIA. Chez Scheme is a proprietary Scheme implementation by R Kent Dybvig (author of The Scheme Programming Language) first released in 1985 Extension Language Kit ( ELK) is a free Scheme implementation which is embeddable in C and C++ programs but can also be used as a 0, Gambit 3. Gambit, also called Gambit-C is a Free software Scheme Implementation, consisting of a Scheme interpreter, and a Compiler which 0, GNU Guile, JScheme, MacScheme, MIT/GNU Scheme, PLT Scheme (DrScheme and MzScheme), Pocket Scheme, RScheme, [[scheme->C]], Scheme 48, SCM, SCM Mac, scsh, STk, T 3. GNU Guile is an interpreter / Virtual machine for the Scheme programming language. JScheme is an implementation of the Scheme programming language, created by Kenneth R MIT/GNU Scheme is a Free software Scheme implementation MIT/GNU Scheme was Free software even before the Free Software Foundation PLT Scheme is an innovative programming language that builds on a rich academic and practical tradition DrScheme is an Open source Integrated development environment for the Scheme programming language which has a Graphical user interface. PLT Scheme is an innovative programming language that builds on a rich academic and practical tradition Pocket Scheme is an implementation of the Scheme programming language for the Microsoft Windows CE Pocket PC and Handheld PC developed by Ben Goetter. RScheme is a Scheme implementation developed by Donovan Kolbly, with an object-orientation approach adapted from Dylan. Scheme 48 is a Free software Scheme implementation using a Bytecode interpreter SCM is a Free software Scheme implementation in C written by Aubrey Jaffer, the same author as the SLIB Scheme library and the SCM is a Free software Scheme implementation in C written by Aubrey Jaffer, the same author as the SLIB Scheme library and the Scsh is a POSIX API layered on top of the Scheme programming language in a manner to make the most of Scheme's capability for scripting STk is a Free software Scheme implementation adhering to the R4RS standard 1, umb-scheme, and VSCM. SLIB is used by GnuCash. GnuCash is a free Accounting software which implements a Double-entry bookkeeping system.
