Here is a manual to install Hellanzb and LottaNZB.
Hellanzb is a Python application designed for *nix environments that retrieves nzb files and fully processes them. The goal being to make getting files from Usenet (e.g.: Giganews Newsgroups) as hands-free as possible. Once fully installed, all thats required is moving an nzb file to the queue directory. The rest; fetching, par-checking, un-raring, etc. is taken care of by hellanzb.
LottaNZB is a Usenet client that automates the download of files from Usenet with the help of NZB files. It can enqueue NZB files directly from within your file manager and Web browser. It supports Newzbin.com, bandwidth throttling, and multiple Usenet servers. The download queue can be rearranged and NZB files can be added using drag’n’drop. It can be easily configured without having to manually edit configuration files. Supported languages included English, Dutch, Danish, French, and German.
