[SciPy-user] Event monitor for ode solver?

Is there any mechanism in SciPy for monitoring some relationship to the variables from an call to odeint as they are found? (I'm am thinking of something like the Event mechanism in matlab) I am doing simple bifurcation analysis, harvisting the local max/min values using ODEPACK in fortran 90. But I would like to do some of this type of analysis in SciPy if possible . . . thanks, Gabriel
