* Java Bittorrent API as its name indicates is a JAVA API that implements the Bittorrent Protocol
* This project contains two packages:
* 1. jBittorrentAPI is the "client" part, i.e. it implements all classes needed to publish

* This package also contains example classes on how a developer could create new applications.
* 2. trackerBT is the "tracker" part, i.e. it implements a all classes needed to run
* a Bittorrent tracker that coordinates peers exchanges. *
