What is the benefits to turning my minecraft server into bukkit and how do i do it?

I have have a friend who has a server and about 3 months ago he had a griefer destroy some stuff and so he closed the server for a little while and then turned it into a bukkit server. He did this because you can see who is holding what and who places what and where they place it. Is this the only thing you can do with a bukkit server? And how can you turn your server into a bukkit server?

Bukkit servers allow you to use plugins, and the majority of minecraft servers use plugins because it can add so much to minecraft, you can look at all the plugins here: https://plugins.bukkit.org Turning a server into a bukkit server requires you to download the bukkit jar and launch that, instead Of The One you get from minecraft.net
