%description
SUNDIALS is a SUite of Nonlinear and DIfferential/ALgebraic equation
Solvers. It consists of the following six solvers:
  - CVODE solves initial value problems for ordinary differential
          equation (ODE) systems;
  - CVODES solves ODE systems and includes sensitivity analysis
           capabilities (forward and adjoint);
  - ARKODE solves initial value ODE problems with additive
           Runge-Kutta methods, include support for IMEX methods;
  - 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.
