-depth option for find(1)

[Willie Heck]

     Could somebody explain what the -depth option does to find(1)?  It
seems to reorder the directory search pattern for the benefit of cpio(1),
but I don't know exactly how.  It is not documented in the 5.0 manual,
although it is used (without explanation) in that manual in an example
in the cpio man pages.
                                        Thanking you in advance,
                                        Willie Heck
