This script can be used to automatically download videos matching some criteria.

To avoid to download a video twice, all videos are stored in an unique way : .files/<backend name>/<video.id>.avi

For each entry in the configuration file, the script :
- check for new video
- download the new videos
- create a link from <user specify name>/<video.name>.avi to .files/<backend name>/<video id>.avi

In each section of the configuration file :
- backend : the backend to use
- pattern : specify the search pattern
- title_exclude : a pipe seperated list. If an item in this list is substring of the title, then the video is ignored.
- id_regexp : an optional regular expression that the video id must match
- max_results : maximum number of result to parse
- directory : the <user specify name> above.
