Television Episode Downloader

# Filename: ezrss
# Version 091110
# Author: robz
# Download trackers from "EZrss" & monitor the "Torrents/Incomplete" folder.
# I have "unmetered" bandwidth in the small hours but dislike leaving my PC
# on all the time, this script suspends & resumes the PC within that timeslot.
# You will need "rtcwake" from the repositories and "shutdown" may need
# adding to the sudoers list.
# In a terminal (omitting all quote marks) do "sudo visudo", at the bottom of
# the listed items click Enter for a new line and paste this entry:
# "%user ALL=NOPASSWD: /sbin/shutdown" replacing "user" with your user name,
# click Escape and do ":wq" Enter to save and exit.
# Be careful editing sudoers as mistakes can cause problems.
# Ref: man visudo - read this if you're at all unsure ---- read it anyway.
# Use this line for your menu or panel launcher, alter to suit ---
# gnome-terminal --geometry 110x50+20+50 -x /home/"user?"/".scripts?"/ezrss
