+// This helper class allows to pass both C array of wxStrings or wxArrayString
+// using the same interface.
+//
+// Use it when you have two methods taking wxArrayString or (int, wxString[]),
+// that do the same thing. This class lets you iterate over input data in the
+// same way whether it is a raw array of strings or wxArrayString.
+//
+// The object does not take ownership of the data -- internally it keeps
+// pointers to the data, therefore the data must be disposed of by user
+// and only after this object is destroyed. Usually it is not a problem as
+// only temporary objects of this class are used.
