Screenlet frontend for HellaNZB, the excellent NZB leeching software.
NZB is an XML-based file format for retrieving posts from NNTP (Usenet) servers. The format was conceived by the developers of the Newzbin.com Usenet Index. NZB is effective when used with search-capable websites. These websites create NZB files out of what is needed to be downloaded. Using this concept, headers would not be downloaded hence the NZB method is quicker and more bandwidth-efficient.
Each Usenet message has a unique identifier called the "Message ID". When a somewhat large file is posted to a Usenet newsgroup, it is usually divided into multiple messages (called segments or parts) each having its own Message-ID. An nzb-capable Usenet client will read the Message-ID from the NZB file, download them and decode the messages back into a binary file (usually using yEnc or Uuencode).
Screenlets is the name of both a set of independently-developed widget applications and the widget engine which runs them. The engine runs primarily on X11-based compositing window managers, most notably the Compiz (under Linux) architecture.
