+value problems of a system of first-order ordinary differential equations (ODE),
+of partial differential equations (PDE), of differential algebraic equations
+(DAE), and of delay differential equations.  The functions provide an interface
+to the FORTRAN functions lsoda, lsodar, lsode, lsodes of the ODEPACK collection,
+to the FORTRAN functions dvode and daspk and a C-implementation of solvers of
+the Runge-Kutta family with fixed or variable time steps.  The package contains
+routines designed for solving ODEs resulting from 1-D, 2-D and 3-D partial
+differential equations (PDE) that have been converted to ODEs by numerical
+differencing.")
