There's a 10ohm resistor as load, I = V/R = 200/10 == 20A?(assuming DC) I'm 
not sure how the diode bridge affects this, but 2A seems a little bit low to 
me.
In interactive mode I plotted I(1) and I(2), and they varied between 0 and 
200, which is sortof what I would expect, seeing as the output is not really 
DC.

.save V(1,2) just saves V(1) and V(2) into the raw plot. 
I don't know how to use those define and .control things.

ngspice still segfaults when I run it in batch mode, without raw output.
I don't want to use interactive mode, because I want to specify what I want to 
see in my input file.
