+#   This scripts enumerates boost types:
+#   Currently supported types: list(also slist) and rbtree
+#
+#   Usage:
+#   !py boost list     <list_address>   <stored_element_type> [additional params for dt cmd]
+#   !py boost rbtree   <rbtree_address> <stored_element_type> [additional params for dt cmd]
+#
+#   Currently works only when member_hook is the first class member.
