-	Advanced Fusion Maps Support
-	(c) 2003-2004, The Fusion Project
-	- AlexKreuz
-
-	The following code has been provided by me for eAthena
-	under the GNU GPL.  It provides Advanced Fusion
-	Map, the map format desgined by me for Fusion, support
-	for the eAthena emulator.
-
-	I understand that because it is under the GPL
-	that other emulators may very well use this code in their
-	GNU project as well.
-
-	The AFM map format was not originally a part of the GNU
-	GPL. It originated from scratch by my own hand.  I understand
-	that distributing this code to read the AFM maps with eAthena
-	causes the GPL to apply to this code.  But the actual AFM
-	maps are STILL copyrighted to the Fusion Project.  By choosing
-
-	In exchange for that 'act of faith' I ask for the following.
-
-	A) Give credit where it is due.  If you use this code, do not
-	   place your name on the changelog.  Credit should be given
-	   to AlexKreuz.
-	B) As an act of courtesy, ask me and let me know that you are putting
-	   AFM support in your project.  You will have my blessings if you do.
-	C) Use the code in its entirety INCLUDING the copyright message.
-	   Although the code provided may now be GPL, the AFM maps are not
-	   and so I ask you to display the copyright message on the STARTUP
-	   SCREEN as I have done here. (refer to core.c)
-	   "Advanced Fusion Maps (c) 2003-2004 The Fusion Project"
-
-	Without this copyright, you are NOT entitled to bundle or distribute
-	the AFM maps at all.  On top of that, your "support" for AFM maps
-	becomes just as shady as your "support" for Gravity GRF files.
-
-	The bottom line is this.  I know that there are those of you who
-	would like to use this code but aren't going to want to provide the
-	proper credit.  I know this because I speak frome experience.  If
-	you are one of those people who is going to try to get around my
-	requests, then save your breath because I don't want to hear it.
-
-	I have zero faith in GPL and I know and accept that if you choose to
-	not display the copyright for the AFMs then there is absolutely nothing
-	I can do about it.  I am not about to start a legal battle over something
-	this silly.
-
-	Provide the proper credit because you believe in the GPL.  If you choose
-	not to and would rather argue about it, consider the GPL failed.
