+Use only the #BT_FALSE and #BT_TRUE definitions for #bt_bool parameters.
+It is guaranteed that the library functions which return a #bt_bool
+value return either #BT_FALSE or #BT_TRUE.
+
+You can always test the truthness of a #bt_bool value directly, without
+comparing it to #BT_TRUE directly:
+
+@code
+bt_bool ret = bt_some_function(...);
+
+if (ret) {
+	// ret is true
+}
+@endcode
