+// -----------------------------------------------------------------------------
+// macros for definition of "template" list type
+// -----------------------------------------------------------------------------
+
+// and now some heavy magic...
+
+// declare a list type named 'name' and containing elements of type 'T *'
+// (as a by product of macro expansion you also get wx##name##Node
+// wxNode-derived type)
+//
+// implementation details:
+// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
+// for the list of given type - this allows us to pass only the list name
+// to WX_DEFINE_LIST() even if it needs both the name and the type
+//
+// 2. We redefine all non-type-safe wxList functions with type-safe versions
+// which don't take any space (everything is inline), but bring compile
+// time error checking.
+//
+// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
+// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
+// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
+// interesting capability to store polymorphic objects in the list and is
+// particularly useful with, for example, "wxWindow *" list where the
+// wxWindowBase pointers are put into the list, but wxWindow pointers are
+// retrieved from it.
