What is it?

Mylar3 is an automated Comic Book downloader (cbr/cbz) for use with SABnzbd, NZBGet and torrents. Also provides an OPDS server distribution.

Mylar allows you to create a watchlist of series that it monitors for various things (new issues, updated information, etc). It will grab, sort, and rename downloaded issues. It will also allow you to monitor weekly pull-lists for items belonging to said watchlisted series to download, as well as being able to monitor and maintain story-arcs.
