#
# Introduction:
#   This script will allow you to have various icons appear over events' heads
#   when the player gets within a certain range of them, and the appropriate
#   tag is found asa comment in their page.
#
# Features:
#   - Easy to use
#   - Can use any number of custom tags you want
#   - Adjustable coordinates for icons
#   - Adjustable cycle times for changing icons
#   - Adjustable proximity before icons show
#   - Icons transition in/out smoothly
#   - Can use glow feature instead of icons
#   - Set custom glow color and speed
#
# Instructions:
#   - See configuration below.
#   - Make sure all icons are located in Graphics/Pictures directory
#
# Credits:
#   - ForeverZer0, for the script
#   - Zexion, for requesting it
#   - Taiine, for her constant reminders to add Blizz-ABS compatibility ;)
