# Credits:
#   TheoAllen for his 'Command Help Popup' script which was the base for this.
#   Vlue for parts of his 'Popup Window' script.
#   vFoggy from rpgmakervxace.net forums for the 'index_of_visible_row' method.
#   RedShard from rpgmakervxace.net forums for asking me to release it.
#
#------------------------------------------------------------------------------
# Description:
#   This is a clone from the help system of SquareSoft's masterpiece
#   'Final Fantasy IX' which i actually made for my own project.
#   The rpgmakervxace.net forums user RedShard asked me if i plan to release
#   it but it was a mess, not plug and play and not user friendly at all so
#   i cleaned up the code and added a simple configuration module.
#
#------------------------------------------------------------------------------
# Compatibility:
#   Requires the script 'Victor Engine - Arrow Cursor' v 1.01 or higher
#   which in turn rquires 'Victor Engine - Basic Module' v 1.09 or higher.
#
#------------------------------------------------------------------------------
# Instructions:
#   To instal the script, open you script editor and paste this script on
#   a new section on bellow the Materials section. This script must also
#   be bellow the scripts 'Victor Engine - Basic Module' and
#   'Victor Engine - Arrow Cursor'.
#
#------------------------------------------------------------------------------
# Additional Info:
#   The all graphics must be in the folder Graphics/System/FF9_Help.
#
#   If you want to use custom graphics you have to edit the script yourself.
#   It was hard enough for me to get this done and its far away from beeing
#   perfect so dont ask me for help when you want to use custom graphics.
#   If you need help with anything else or a have bug to report feel free
#   to contact me at http://www.rpgmakervxace.net/ forums!
#
#   I hope you enjoy this script and i would like to see it when you
#   give TheoAllen, Vlue, vFoggy and maybe me credits in your game! :)
