description         Full-featured atomic-scale first-principles simulation software

long_description    ABINIT is a package whose main program allows one to find the total energy, \
                    charge density and electronic structure of systems made of electrons and nuclei \
                    (molecules and periodic solids) within Density Functional Theory (DFT), \
                    using pseudopotentials and a planewave or wavelet basis. \
                    ABINIT also includes options to optimize the geometry according to the DFT forces \
                    and stresses, or to perform molecular dynamics simulations using these forces, \
                    or to generate dynamical matrices, Born effective charges, and dielectric tensors, \
                    based on Density-Functional Perturbation Theory, and many more properties. \
                    Excited states can be computed within the Many-Body Perturbation Theory \
                    (the GW approximation and the Bethe-Salpeter equation), and \
                    Time-Dependent Density Functional Theory (for molecules). \
                    In addition to the main ABINIT code, different utility programs are provided. \
                    ABINIT is a project that favours development and collaboration.
