+   * - a |migrate| method, taking a single argument, aCallback(bool success),

+   *   aCallback(bool aSuccess) when it's done.  In the case of an exception
+   *   thrown from |migrate|, it's taken as if aCallback(false) is called.

+   * For each migration type listed in nsIBrowserProfileMigrator, multiple

+   *
+   * Note that the importation of a particular migration type is reported as
+   * successful if _any_ of its resources succeeded to import (that is, called,

+   *        can be imported.  So, for example, before adding a resource for the
