2 * This file handles commands from the File daemon.
4 * We get here because the Director has initiated a Job with
5 * the Storage daemon, then done the same with the File daemon,
6 * then when the Storage daemon receives a proper connection from
7 * the File daemon, control is passed here to handle the
8 * subsequent File daemon commands.
