Installation:
	read INSTALL


Usage:
	greed URL(1) URL(2)... URL(N)
	i.e. greed http://www.public.asu.edu/~arturner/greed.tar.gz ftp://some.where/out/there.tar.gz


Switches:
	-Z:	Sends me a bug report
	-F:	Disables reading URLS from greed.in
	-I:	Reads URLS from standard input
	-N:	Grab the newest version of GREED
	-O#:	Change the output level (0=none...1=less...9=most) [DEFAULT = 5]
	-S:	Prints file to STDOUT
	-R:	Disables referrer URL, if a URL is specified after the -R then it defaults to
	-Rurl:	To that URL at the referrer (i.e. -Rhttp://www.asu.edu/ would make www.asu.edu
		the referrer URL.  Useful for bandwidth wary sites!)
	-T:	Tests archived files after download.
	-D#:	Tells greed to download X files at a time.  If no number is specified, it assumes 2 at a time.
	-L#:	Sets the level of recursion for FTP transfers.
	-M<adr>	Send a mail to [adr] (by sendmail) when a download is complete.
	-B:	Sends GREED into background download mode.
	-Gfilename.grx:
		Loads a .grx file (Windows GetRight), parses it, and downloads the files specified within
	-Curl:	changes the %##'s in a URL to characters... should old be used for URL's that don't work
		correctly, or have %##'s in them ;)
	-?:	Shows you these options ;)


Cool Tricks:
	greed -i < file.to.download
		downloads a list of files

	greed -d -b http://foo.bar/file.zip http://ab:[e-mail]/kl/mno.p\fR
        	Drops greed into the background and downloads the 2 URLS simultaineously!

	greed www.freshmeat.net...freshmeat.index.html
		"..." saves the URL retrieved from www.freshmeat.net to freshmeat.index.html


Proxies:
	Edit the .greedrc



Wish List:
o  More compatibility
o  A port of Wetrix to linux (cough cough)
o  other protocols?
o  Frontend
o  Better proxy support (Some people have problems with FTP)



	---==== Questions and Answers! ====---


Question?:	Where do I get greed?
Answer!:	http://www.public.asu.edu/~arturner/index.html ;)

Question?:	What, no frontend for us X users?
Answer!:	One may come soon ;)  Probably in a month or so ;)

Question?:	What happened to FTP access? it's going SO SLOW now!
Answer!:	If you're one of those special people that has a
		connection faster then a modem you may have noticed
		that greed's ftp has slowed down a bit!  To fix this,
		edit your greedrc file and lower yout SPEEDUP_FTP
		value :)  before it was set to 0, now it's set to
		1000000 (that's ~1 second between commands), try
		something around 50000.  I personally use 0 :)

Question?:	I found so and so bug when trying to do whatever...
		What should I do?
Answer!:	If you know what the bug is and how to fix it, please
		e-mail me with the answer.  Otherwise just e-mail me
		with the bug ;)

Question?:	Where is this famed greedrc I keep on hearing about?
Answer!:	Well if it doesn't exist in the current directory,
		or your home directory as .greedrc, it can be found
		in /etc/greedrc!

Question?:	I found /etc/greedrc, but I want one of my own!
		What should I do?
Answer!:	cp /etc/greedrc ~/.greedrc

Question?:	I am a sys admin and I put greed's rc in /etc/greedrc,
		but when any of my users try to run greed they get a
		segmentation fault!  What should I do?
Answer!:	give me the root password to your box :)  Just kidding :)
		just chmod 755 /etc/greedrc

Question?:	You said a frontend will come out a in a month...
		A month from when?
Answer!:	The month before the month of the day of the release
		a month later!

Question?:	You rock!  Can I send you all my money?
Answer!:	Yes ;)

Question?:	Why did you make greed?
Answer!:	For a future project coming up soon... Greed is 1/3
		of the project...  watch the greed web page for more
		details. ;)

Question?:	I need to connect through a proxy server and...
Answer!:	edit the .greedrc...  if that doesn't work, then
		drop me some mail on what you need added/why it
		doesn't work.

Question?:	I run RedHat and...
Answer!:	Just e-mail me ;)

Question?:	Why won't greed let me download files from
		ftp.microsoft.com?
Answer!:	What are you talking about?  I fixed that bug in .8!
		if it's still doing it, then up the SPEEDUP_FTP time
		in your greedrc file

Question?:	Why do you end all of your answers with smilies?
Answer!:	Low blood sugar ;)

Question:	Why do I keep on getting "Error connecting to FTP
		socket for RETR!" messages... What's up with that?
Answer!:	Sometimes you can't connect to an open FTP socket for
		retrieval of a file, therefore the download fails.
		Just try again. ;)
