Re: New Swarm utility: Runtime scripting

[Rick Riolo]

This sounds like a very useful utility.

Amoung other things, it seems to me it could be used
in conjunction with the Probe-change-notification hooks
to record user-instigated events (eg change a value
via a Probe) so that a user-GUI-controlled 
run could be replayed. 

So...thanks to Benedikt.
(Now I guess I better find some time to try it out...)
