===== Lible ===== `Lible `_ is a modern C++ library that aims to provide the basic utilities used in quantum chemical method development. The library provides the utilities in a form of custom types and thin-grained functions and aims to cover various concepts in quantum chemistry: * :ref:`Calculation-of-molecular-integrals` * Geometry optimization * Spin adaptation * :ref:`Linear-algebra-solvers` * Formula derivation * :ref:`Types` Therefore, Lible is designed in a modular manner, where each of these topics comes with a a separate programming interface, or *namespace*, to be specific. .. toctree:: :hidden: :maxdepth: 1 integrals solvers types
