E.2.3 Notes for developers

There has been an intensive process of refactoring, redesign and modularization of Singular to facilitate easier maintenance and future development:

• Build System : automake, libfac has been integrated into Factory
• Removed MP (Multi protocol) in favor of SSI links.
• Separation/modularization into libraries and packages
• For easy integration of new coefficient rings, we defined a generic interface for coefficient rings and a supporting framework for making them accessible to the user.

  In particular we have separated everything related to coefficient rings into a separate library libcoeffs. Dependency tree between restructured packages is show at https://www.singular.uni-kl.de/dox/singular.png

  In order to use libSingular as a C++ library, see libSingular.
