Section devel - Debian Package: cim

 GNU Cim is a compiler for the programming language Simula (except
 unspecified parameters to formal or virtual procedures (see the
 documentation for how portable code for formal procedures can be
 written)).  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.
 .
 The portability of the GNU Simula Compiler 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.
