I wrote this module in order for me automate my personal Video library rip and import work flow.
The idea being that dvds would be ripped into a staging folder. The files would be named according to Season and Episode format. The resulting file would then be moved into the correct show/season folder automatically. This is done as a cron job.
The module's role is to allow someone to create their own programs to to carry out these actions. Taking care of details such as matching show name to destination folder, create the required season folder if it does not exist and calling rsync to migrate the video file to its new home.
