+    <p><!-- https://go.dev/issue/53747, CL 476015 -->
+      The new <a href="/pkg/flag/#BoolFunc"><code>BoolFunc</code></a>
+      function and
+      <a href="/pkg/flag/#FlagSet.BoolFunc"><code>FlagSet.BoolFunc</code></a>
+      method define a flag that does not require an argument and calls
+      a function when the flag is used. This is similar to
+      <a href="/pkg/flag/#Func"><code>Func</code></a> but for a
+      boolean flag.
