A minimal BitTorrent client. It wont have all the pretty features that other Torrent apps have, but focuses on low memory and CPU usage. Because it was written in C++, you dont get the high memory requirements of Java or high CPU usage of Python.
Its minimalist interface is testamony to the programs simplicity. It shows the list of your active downloads with various details and not much else. The window is extremely basic and logically, doesn't put much of a drain on your system resources or on the processor.
