 * ============================================================================
 * Important
 * ============================================================================
 * This plugin requires YEP Item Core and YEP Shop Menu Core. This plugin
 * must be put underneath them in the plugin list.
 * 
 * Equipped items that are not independent cannot be marked as junk or disposed.
 * For this reason, I recommend making equipment independent in Item Core.
 *
 * In order to sell all junk items at the shop, the command Custom
 * must be somewhere in the command order parameter for YEP Shop Menu Core.
 * By default, it is in, so if you haven't removed it then you don't need to do
 * anything.
 *
 * If you want the sell all junk command to appear somewhere else in the list,
 * just place Custom in a different place in the command order parameter in
 * YEP Shop Menu Core.
 * ============================================================================
 * How To Use
 * ============================================================================
 * In the item menu, you can set items to be marked as junk. After, you can
 * unmark them as junk if you want. Junk items appear in the junk category.
 * 
 * In the shop, you can select the Sell All Junk command to sell all junk
 * in your inventory.
 *
 * ============================================================================
 * Item/Weapon/Armor Notetags
 * ============================================================================
 * <Junk> will automatically designate an item as junk. It can't be unmarked
 * as junk.
 *
 * <CantMarkJunk> will disallow an item from being marked as junk. Good for
 * important items.
 * 
 * <CantDispose> will disallow an item from being disposed with the dispose 
 * command.
 * ============================================================================
 * Command Name Text Codes
 * ============================================================================
 * Text codes can be used to configure the names of commands.
 * 
 * %1 - Icon of item
 * %2 - Name of item
 * %3 - Number of item in inventory
 * 
 * This does not apply to the Sell All Junk command.
 * ============================================================================
 * Terms Of Use
 * ============================================================================
 * Free to use and modify for commercial and noncommercial games, with credit.
 * ============================================================================
 * Credits
 * ============================================================================
 * DreamX
 * Thanks to Yanfly for Item Core and Shop Core plugins.
