-
-============
-Architecture
-============
-
-CloudSync offers functionality similar to Firefox Sync for data sources. Third-party addons
-(sync adapters) consume local data, send and receive updates from the cloud, and merge remote data.
-
-
-Files
-=====
-
-CloudSync.jsm
-    Main module; Includes other modules and exposes them.
-
-CloudSyncAdapters.jsm
-    Provides an API for addons to register themselves. Will be used to
-    list available adapters and to notify adapters when sync operations
-    are requested manually by the user.
-
-CloudSyncBookmarks.jsm
-    Provides operations for interacting with bookmarks.
-
-CloudSyncBookmarksFolderCache.jsm
-    Implements a cache used to store folder hierarchy for filtering bookmark events.
-
-CloudSyncEventSource.jsm
-    Implements an event emitter. Used to provide addEventListener and removeEventListener
-    for tabs and bookmarks.
-
-CloudSyncLocal.jsm
-    Provides information about the local device, such as name and a unique id.
-
-CloudSyncPlacesWrapper.jsm
-    Wraps parts of the Places API in promises. Some methods are implemented to be asynchronous
-    where they are not in the places API.
-
-CloudSyncTabs.jsm
-    Provides operations for fetching local tabs and for populating the about:sync-tabs page.
-
-
-Data Sources
-============
-
-CloudSync provides data for tabs and bookmarks. For tabs, local open pages can be enumerated and
-remote tabs can be merged for displaying in about:sync-tabs. For bookmarks, updates are tracked
-for a named folder (given by each adapter) and handled by callbacks registered using addEventListener,
-and remote changes can be merged into the local database.
-
-Versioning
-==========
-
-The API carries an integer version number (clouySync.version). Data records are versioned separately and individually.
