Enhanced CTorrent

Enhanced CTorrent - http://www.rahul.net/dholmes/ctorrent/

CTorrent is a BitTorrent client implemented in C++ to be lightweight and quick. The original has fallen a little behind in updates and bug fixes though.

The files here contain the good work of those who wrote the original CTorrent base code and a number of patches that provide fixes and enhancements, as well as additional fixes and enhancements that I am contributing. I am not the original author, current maintainer, or any other official representative of CTorrent. The files on this page are not the original or official CTorrent distribution. I encourage you to visit the CTorrent project page on SourceForge for further information.

Enhanced CTorrent now has a SourceForge project page with forums, bug reporting, and downloads.

Create torrents via command line!

py3createtorrent is a comprehensive shell/commandline utility for creating torrents (Linux & Windows). It's a GPL-licensed Python v3.1 script. I tested it with Ubuntu 8.04 / rTorrent and Windows 7 / µTorrent.

Some of the features:

• you can create huge torrents for any amount of data
• you can add a comment to the torrent file
• you can create private torrents (disabled DHT, …)
• you can create torrents with multiple trackers
• you can exclude specific files/folders
• you can exclude files/folders based on regular expressions
• you can specify custom piece sizes
• you can specify custom creation dates
