+#X text 18 409 This patch demonstrates 4-point interpolation in tabread4~.
+The 11-point table \, waveform13 \, contains a transition from from
+1 to -1 \, which is "smoothed" as seen in wave-out13. There's no such
+transition at the wraparoind point--the interpolation always happens
+between 4 consccutive samples of the table \, disregarding wraparound.
