/*
	This small tool was made for Graphist, to edit automatically *.animation_set sheets, so anims
	get correct MeleeImpactDelay data

	It uses an anim.txt file that was generated by inserting code (give at end of this file)
	in the client.

	This tool had to be "used one time only". hence its crappiest usage :)
