+The arrow with style @Code solidwithbar has a bar at the tip of the
+arrowhead, whose length equals the width of the arrow and whose
+width is {@Code pathwidth}, like this:
+@ID @Diag {
+A:: @Box margin { 0i } outlinestyle { noline } 3c @Wide
+//
+@Link from { A@W } to { A@CTR } arrow { forward } arrowstyle { solidwithbar }
+@Link from { A@CTR } to { A@E } arrow { back } backarrowstyle { solidwithbar }
+}
+This example shows that half of the bar extends beyond the area
+allocated to the arrow, so that if two of these arrows meet from
+opposite directions, their bars will exactly overstrike.

 Corresponding with {@Code arrowstyle}, {@Code arrowwidth}, and
 {@Code arrowlength}, there are {@Code backarrowstyle},
