-#X text 24 20 The butterworth filter can be configured for low-pass
-\, high-pass \, and shelving \, depending on the placement of the poles
-and zeros. For low-pass \, the poles are placed to set the cutoff frequency
-and the zeros are at -1 (the Nyquist). Leaving the poles fixed and
-moving the zeros then gives shelving filters. In this example \, the
-actual filtering is relegated to an abstraction (butterworth3~) which
-takes frequencies corresponding to the pole and zero placement.;
-#X text 24 147 The butterworth3~ abstraction computes filter coeffients
-using control messages \, and so it is not suitable for continuously
-time-varying Butterworth filters. For that \, it is often appropriate
-to use time-saving approximations \, but precisely which approximations
-to use will depend on the way the filter is to be used.;
