}It's trivial to build such a thing, by the way:  an integrator integrating

Yes, the problem is trivial as stated.  Let's see if we can make it more
interesting:

	How would you make the circuit so that the sawtooth starts at zero on
the leading edge of the square wave, and reaches maximum just as the square
wave falls.  Let this be a steady state repetitive waveform.  Manual
adjustments are not permitted.  

Now, isn't that more interesting?
