Hrm, how do you want the result, where would it put it? If it just set the $var$, you'd have to have them do this every time you resarted litestep. If you want it to write it to step.rc, you'll need to specify *where*. (tho personally, I'd prefer to leave that to existing methods)

I could probly whip something up tomorrow, but it'd be flexible and very hard to understand. (using ^@...^ ;)
