 GNU libavl, a library for balanced binary trees. Balanced binary trees
 provide guaranteed O(lg n) performance for list insertion, deletion, and
 search operations. libavl is the most complete free balanced binary tree
 library on the net today, supporting AVL trees in plain, threaded, and
 right-threaded forms as well as plain red-black trees.
