//
// This class is used to cut/copy/paste text strings and inventory items around
// the world. Use LLClipboard::instance().method() to use its methods.

// where the viewer does offer a serialized version of the UUID on the clipboard.
// In those case, the text is overridden when copying/cutting the item.
// In all other cases, the text and the UUIDs are very much independent.
