 * USAGE: php moveBatch.php [-u <user>] [-r <reason>] [-i <interval>] [-noredirects] [listfile]
 *
 * [listfile] - file with two titles per line, separated with pipe characters;
 * the first title is the source, the second is the destination.
 * Standard input is used if listfile is not given.
 * <user> - username to perform moves as
 * <reason> - reason to be given for moves
 * <interval> - number of seconds to sleep after each move
 * <noredirects> - suppress creation of redirects
 *
 * This will print out error codes from Title::moveTo() if something goes wrong,
 * e.g. immobile_namespace for namespaces which can't be moved
