libtorrent is a C++ library that aims to be a good alternative to all the
other bittorrent implementations around.  It is a library and not a full
featured client, although it comes with a working example client.

The main goals of libtorrent are:

* to be cpu efficient
* to be memory efficient
* to be very easy to use

Note that this is NOT the same library as the libtorrent port!
