-# * Sync.set() and Sync.clear() propagate local changes to chrome.storage.sync.
-# * Sync.handleStorageUpdate() listens for changes to chrome.storage.sync and propagates those
-#   changes to localStorage and into vimium's internal state.
-# * Sync.fetchAsync() polls chrome.storage.sync at startup, similarly propagating
-#   changes to localStorage and into vimium's internal state.
-#
-# Changes are propagated into vimium's state using the same mechanism
-# (Settings.performPostUpdateHook) that is used when options are changed on
-# the options page.
-#
-# The effect is best-effort synchronization of vimium options/settings between
-# chrome/vimium instances.
-#
-# NOTE:
-#   Values handled within this module are ALWAYS already JSON.stringifed, so
-#   they're always non-empty strings.
