# This scriptlet allows you to show custom icons and comments in the Inventory

# Menu scene. It will show the party leader's opinion on a given item.

# Optional: Place large icons in Graphics/Pictures folder with their item names.

# You may also allow the player to check out his or her skills on the same menu

# by activating a global switch via an event command. It can be deactivated at

# any given time!
