-Finally, none of the methods of this class is virtual including its
-destructor, so this class should not be derived from.
+There is also a variant of wxArrayString called wxSortedArrayString which has
+exactly the same methods as wxArrayString, but which always keeps the string
+in it in (alphabetical) order. wxSortedArrayString uses binary search in its
+\helpref{Index}{wxarraystringindex} function (instead of linear search for
+wxArrayString::Index) which makes it much more efficient if you add strings to
+the array rarely (because, of course, you have to pay for Index() efficiency
+by having Add() be slower) but search for them often. Several methods should
+not be used with sorted array (basically, all which break the order of items)
+which is mentioned in their description.
+
+Final word: none of the methods of wxArrayString is virtual including its
+destructor, so this class should not be used as a base class.
