#Purpose: Automate the downloading of files from rapidshare using the free account 
#using simple unix tools.
#Date: 14-7-2008
#Authors: Slith, Tune
#Improvements: Please email them to jwhatson@gmail.com
#Post Feedback and comments to http://emkay.unpointless.com/Blog/?p=63
#Notes: To use curl instead of wget use 'curl -s' and 'curl -s -d'
#Version: 1.2 - Rapidshare has added a wait time in between file downloads. On top of your download
#to start. This has been fixed.
#Added a 'kill time' feature. Specify killTime as an hour of the day and if the time is greater than this. 
#the script will end. Useful for using cron to start script at offpeak time and killing it when off speak ends.
