    // <--[language]
    // @name Item Script Containers
    // @description
    // Item script containers are an easy way to pre-define custom items for use within scripts. Item
    // scripts work with the dItem object, and can be fetched with the Object Fetcher by using the
    // dItem constructor i@item_script_name. Example: - drop <player.location> i@super_dooper_diamond
    //
    // The following is the format for the container. Except for the 'material' key (and the dScript
    // required 'type' key), all other keys are optional.
    //
    // <code>
    // # The name of the item script is the same name that you can use to construct a new
    // # dItem based on this item script. For example, an item script named 'sword of swiftness'
    // # can be referred to as 'i@sword of swiftness'.
    // Item Script Name:
    //
    //   type: item
    //
    //   # Must be a valid dMaterial (ie. m@red_wool or m@potion,8226) See 'dMaterial' for more information.
    //   material: material
    //
    //   # The 'custom name' can be anything you wish. Use color tags to make colored custom names.
    //   display name: custom name
    //
    //   # Lore lines can make items extra unique. This is a list, so multiple entries will result in multiple lores.
    //   # If using a replaceable tag, they are filled in when the item script is given/created/dropped/etc.
    //   lore:
    //   - item
    //   - ...
    //
    //   # Each line must specify a valid Bukkit enchantment. See 'enchantments' for more information.
    //   enchantments:
    //   - enchantment_name:level
    //   - ...
    //
    //   # Specifying a material will allow your item script to be crafted. Specify the materials required
    //   # to craft your item. For an empty slot, use m@air. Currently, Denizen only supports shaped recipes.
    //   recipe:
    //   - m@material|m@material|m@material
    //   - m@material|m@material|m@material
    //   - m@material|m@material|m@material
    //
    //   # Set to true to not store the scriptID on the item, treating it as an item dropped by any other plugin.
    //   no_id: true/false
    //
    //   # For colorable items, such as leather armor, you can specify a valid dColor to specify the item's appearance.
    //   # See 'dColor' for more information.
    //   color: c@color
    //
    //   # If your material is a 'm@written_book', you can specify a book script to automatically scribe your item
    //   # upon creation. See 'book script containers' for more information.
    //   book: book_script_name
    // </code>
