# PT site's RSS checker
# By Bill Haofei Gong on 5th Jan, 2013
#
# This script is for checking the RSS cart from a PT site and download added torrents
# to specified folder. Therefore transmission-daemon will be able to add those torre-
# nts and start to download. 
#
# Replace value of RSS_URI to the address of your RSS feed. If the feed uses a diffe-
# rent keyword to describe links, you may need to change RSS_PATTERN and SED_PATTERN
# to fit the pattern of torrents in feed. 
#
# To make transmission-daemon watches folder and add automatically, you need to: 
# 1. create a folder for torrents and give owner and group as "debian-transmission"
# 2. add/modify following parameters to your transmission settings file:
#    "start-added-torrents": true,
#    "trash-original-torrent-files": false, 
#    "watch-dir": "YOUR-TORRENT-FOLDER",
#    "watch-dir-enabled": true
# 3. add this script to crontab to check RSS feed at a regular time. 
#    for example, to check RSS feed every 15 minutes, add following: 
#    */15 * * * * "LOCATION-OF-THIS-SCRIPT"
#
# Steps above will set transmission-daemon not to delete old torrents after added. T-
# herefore in this script, wget will not re-download exist torrents. This will incre-
# ase the speed of each check.
