This library provides a C and C++ Application Programming Interface (API) to develop client applications to access Computer Algebra Systems which support that protocol. Computer Algebra Systems could use these API to provide services to other applications using this protocol.
This C/C++ library is an implementation of the Symbolic Computation Software Composibility Protocol (SCSCP).
The current implementation is based on the specification version 1.3 (see , for more about SCSCP).


The library is written by M. Gastineau (CNRS - Observatoire de Paris - IMCCE) and is distributed under the free software CECILL-C or CECILL license.

This software is governed by the CECILL-C or CECILL version 2 license under French law and abiding by the rules of distribution of free software. You can use, modify and/or redistribute the software under the terms of the CeCILL-C or CeCILL license as circulated by CEA, CNRS and INRIA at the following URL

As this software is an open-source product distributed under two distinct licenses giving you the choice of one of the two licensing terms, you have to choose one of the two licenses CECILL-C or CECILL version 2. This allows the use of our code in a variety of software projects as wide as possible.
