How to import towny into plugin?

Im coding a plugin for a modded server and the protection is Towny. The problem is I have people with quarrys place them outside the towns and it builds into the towny griefing the edges. I need to know how to import Towny into my plugin so I can check around the town when a block is placed(Quarry). Then also I need it to where I can ban items Right click or Left click inside towns like wrenches. This can help prevent a wrench from picking up blocks like Mass Fabs, Generators, Solars, Etc. undetectable. I searched every where for help but nothing has come up any advice will be appreciated.

Here's the Towny API http://palmergames.com/javadoc

 

Don't bump too many times.
You import Towny.jar the same way you import Bukkit.jar, and use it essentially the same way.

 

Do you know any way of getting events or any sources I may use?

 

I personally just decompiled the jar and looked through its source to see how it works.

 

The source is available on github.com/elgarl
