     Original AVL tree library by Michael H. Buselli <cosine@cosine.org>.
 
-    Modified 2000-11-28 by Wessel Dankers <wsl@nl.linux.org> to use counts
+    Modified 2000-11-28 by Wessel Dankers <wsl@tinc-vpn.org> to use counts
     instead of depths, to add the ->next and ->prev and to generally obfuscate
     the code. Mail me if you found a bug.
