+// To test the convolver, we convolve two square pulses together to
+// produce a triangular pulse.  To verify the result is correct we
+// check several parts of the result.  First, we make sure the initial
+// part of the result is zero (due to the latency in the convolver).
+// Next, the triangular pulse should match the theoretical result to
+// within some roundoff.  After the triangular pulse, the result
+// should be exactly zero, but round-off prevents that.  We make sure
+// the part after the pulse is sufficiently close to zero.  Finally,
+// the result should be exactly zero because the inputs are exactly
+// zero.
