Burst! is a client for the BitTorrent protocol.
Burst! uses a modified version of the original python client as the back-end, and replaces the front-end with a native Win32 application, which has a smaller memory footprint, due to replacing the wxPython GUI with one written in Delphi. Burst! uses less system resources (with multiple transfers), and has more features than the original client, such as a torrents manager and the ability to enter super-seeding mode. Burst! was programmed in Delphi and Python using Kylix
According to the Burst-Announce mailing list (http://sourceforge.net/mailarchive/forum.php?forum=burst-announce), the client was last updated on 2006-Apr-09: it is Burst! v3.1.0b, a beta codenamed "Hurricane". It's based on BitTornado T-0.3.17. Burst's homepage has been inactive in recent months, (latest news: 2006-Nov-19), but the project's forums on Sourceforge remain mildy active: http://sourceforge.net/forum/?group_id=86654
Burst! is open source released under the MIT license and is available at no charge. Burst! does not appear to contain a built-in means of revenue generation (in-program ads etc) or install separate adware.
