4. Source code

The source code of FRED is divided into several subprojects.

The subprojects belong to one of the following groups depending on which tools are used to build them:

  • ::A:: stands for Autotools (used only in fred/db),

  • ::C:: stands for CMake (used with C++ code),

  • ::S:: stands for Python Setuptools.

Each subproject has its own GitHub repository.
