# downloadque.sh script by Frits Vlaanderen (frits@hccniet.nl)
# Based on download.sh script from uzbl
#
# Without arguments, the script will download all urls in the file $que (.downloadque) with wget.
# After downloading a file it downloads the next file in que and deletes the first line from the que. 
# When the download que becomes empty, the script stops.

# If you pass 1 argument to the script, the script will add the argument to the $que file.
# If more arguments get passed, the script will stil add the first argument.
# When 8 or more arguments get passed to the script, it will use the 8th argument. 
# This is how uzbl passes the url to the script.
 
# v0.2 Additions:
#	 	 - Usable without uzbl
#		 - Renames filename to actual filename where possible (no index.php?name=etc)

# Extend this with whatever you want, please send me your extensions or criticism or whatever (frits@hccniet.nl)

# just an example of how you could handle your downloads
# try some pattern matching on the uri to determine what we should do

# Some sites block the default wget --user-agent..
