pySabRename is a post-processing script for sabnzbd and nzbget. It renames the biggest file in the final download folder to the job name. It will also rename subtitles and the nfo. After renaming it will clean up the download dir.
This program is used in sabnzbd and works really well when using the latest SpotWeb pull. It is designed for movies and tv episodes with 'encrypted' (=mostly random or flipped) filenames.
It will not work as you'd probably like when multiple episodes are downloaded in the same job!
