** Presents incoming tiddlers as a pending import list that allows the user to inspect them and, if necessary, explicitly deselect them from the actual import
** Provides UpgraderModules with an opportunity to process each incoming tiddler
*** The [[plugin upgrader|$:/core/modules/upgraders/plugins.js]] module handles version checking of plugins and upgrading them from a special UpgradeLibrary plugin tiddler
*** The [[system upgrader|$:/core/modules/upgraders/system.js]] module is responsible for suppressing the importing of certain system tiddlers (currently [[$:/StoryList]] and [[$:/HistoryList]])
*** The [[themetweak upgrader|$:/core/modules/upgraders/themetweaks.js]] module handles migrating theme tweaks from their pre-5.0.14-beta format (see below)
