The file mtree.out gets rebuilt whenever new stuff gets added to the
archive site and can be used to check that your copy is correct.  It
gets generated by the gen_mtree script.  The mtree(1) command gets run
so it will generate:

	type,mode,size,time,md5digest

To check your copy with your current working directory being the top-level
of the archive site do:

	mtree -f MTREE/mtree.out
