description         SUite of Nonlinear and DIfferential/ALgebraic equation Solvers
long_description    SUNDIALS consists of the following five solvers: CVODE\
                    solves initial value problems for ordinary differential\
                    equation (ODE) systems.  CVODES solves ODE systems and\
                    includes sensitivity analysis capabilities (forward and\
                    adjoint).  IDA solves initial value problems for\
                    differential-algebraic equation (DAE) systems.  IDAS solves\
                    DAE systems and includes sensitivity analysis capabilities\
                    (forward and adjoint).  KINSOL solves nonlinear algebraic\
                    systems.
