NzbD is a GUI Wrapper for nzbget, a command-line client that allows you to download binary files off usenet by processing .nzb files. A pre-compiled version of nzbget for OS X is included. More information on nzbget is available here.
ANONYMOUS Version 0.12 supports one newsserver configuration in the preferences, where it used to be possible to have multiple backup/fill servers in the older NzbD versions. That needs to be fixed soon!
Also, the app developed a crashing problem and auto quits every time I launch it now. (Version 0.12)
ANONYMOUS This works after some editing, tweaking, copying, and renaming in the Terminal. I really wish .nzb support was built into a Mac newsreader ... like Thoth (before it was dropped). (Version 0.1b)
