-# AVL
-
-AVL is a library indexing objects in B-Trees.
-
-`avl_insert()`, `avl_remove()` and `avl_search()` are adaptations
-of the AVL algorithm found in `libavl` v2.0.3, so that they do not
-use any memory allocations and their memory footprint is optimized
-(by eliminating non-necessary data members).
-
-In addition to the above, this version of AVL, provides versions using locks
-and traversal functions.
