Finally I have decided to maintain OpenLD script. You already know OpenLD is a very lightweight link directory script. It is highly extensible without hard coding. You can make extensions to utilize its hooking system. There are many hooks in every steps of all files where you may push some piece of code by your extension.
I love this script. But I have seen that it is not maintained for a quite long time. I don’t know what happened to the original developer Anders Persson. As I don’t want this great work to die, I am going to maintain it. I am doing the home works before I start and will update shortly.
