-/**
- * A helper class which can be used in conjunction with
- * {@link android.backup.BackupHelperAgent} to manage the backup of a set of
- * files. Whenever backup is performed, all files changed since the last backup
- * will be saved in their entirety. During the first time the backup happens,
- * all the files in the list will be backed up. Note that this should only be
- * used with small configuration files and not with large binary files.
- * <p>
- * Any files not present in the list of files during the restore procedure will
- * be ignored. If files present in a previous version of an application are
- * removed in subsequent versions, it is the responsibility of the developer to
- * design a mechanism to remove those files. Otherwise files no longer needed
- * will linger and consume space on the device.
- * <p>
- * STOPSHIP: document! [manages backup of a set of files; restore is totally
- * opaque]
