-// The SavePackage object manages the process of saving a page as only-html or
-// complete-html and providing the information for displaying saving status.
-// Saving page as only-html means means that we save web page to a single HTML
-// file regardless internal sub resources and sub frames.
-// Saving page as complete-html page means we save not only the main html file
-// the user told it to save but also a directory for the auxiliary files such
-// as all sub-frame html files, image files, css files and js files.
-//
-// Each page saving job may include one or multiple files which need to be
-// saved. Each file is represented by a SaveItem, and all SaveItems are owned
-// by the SavePackage. SaveItems are created when a user initiates a page
-// saving job, and exist for the duration of one tab's life time.
