GNU Cim is a compiler for the programming language Simula (except unspecified parameters to formal or virtual procedures). It offers a class concept, separate compilation with full type checking, interface to external C routines, an application package for process simulation and a coroutine concept. Its portability is based on the C programming language. The compiler and the run-time system is written in C, and the compiler produces C code, that is passed to a C compiler for further processing towards machine code.
GNU Image-Finding Tool (GIFT) is a Content-Based Image Retrieval System (CBIRS). It enables Query By Example, giving you the opportunity to receive relevant feedback, thereby improving your query results. The program relies entirely on the content of the images to process queries, so there is no need to annotate all the images before querying the collection.
MARST automatically translates programs written on the algorithmic language Algol 60 to the C programming language. It includes three main components: MARST, the translator; ALGLIB, the library containing precompiled standard Algol 60 procedures, and other necessary routines; and MACVT, the converter, which allows you to convert existing Algol 60 programs from other representations, to MARST representation.
