Section utils - Debian Package: mirrordir

 mirrordir forces the mirror directory to be an exact replica of the
 control directory tree in every possible detail suitable for purposes
 of timed backup. Files whose modification times or sizes differ are
 copied. File permissions, ownerships, modification times, access
 times, and sticky bits are duplicated.  Devices, pipes, and symbolic
 and hard links are duplicated.  Files or directories that exist in
 the mirror directory that don't exist in the control directory are
 deleted.  It naturally descends into subdirectories to all their
 depths. mirrordir tries to be as efficient as possible by making the
 minimal set of changes necessary to mirror the directory.
