The qBittorrent project was created in March 2006 with the idea of developping a new Bittorrent client for Linux (and possibly other systems) that would be easy to use, good looking, featureful but lightweight.
qBittorrent is a Free Software released under the GNU GPL license.
The author is Christophe Dumez, a French student in an engineer school (UTBM), in IT departement.
qBittorrent is based on the great Libtorrent by Arvid Norberg.
