+`pst-ode' defines \pstODEsolve for solving initial value problems for sets of
+Ordinary Differential Equations (ODE) using the Runge-Kutta-Fehlberg (RKF45)
+method with automatic step size adjustment.
+
+\pstODEsolve[<options>]{<result>}{<output format>}{t_0}{t_e}{N}{x⃗_0}{f⃗(t,x⃗)}
+
+The state vectors x⃗ found at N equally spaced output points between t_0 and
+t_e are stored in the PostScript object <result>, formatted according to the
+second argument <output format>, as a long list of values. <output format>
+lists the quantities to be stored in <result>. The user can select from the
+elements of x⃗ and the integration parameter t.

-of Ordinary Differential Equations (ODE) using the Runge-Kutta-Fehlberg
-(RKF45) method with automatic step size adjustment.
+The initial condition vector x⃗_0 and the right-hand side f⃗(t,x⃗) of
+the ODE system can be input in algebraic notation, if desired. RPN (Postfix)
+notation of PostScript can as well be used.
+<result> can be directly used as the <data> argument of \listplot{<data>}
+(package `pst-plot') or \listplotThreeD{<data>} (package `pst-3dplot').
