++ This option hard links the destination files into _DIR_, a link farm
++ arranged by MD5 file hash. The result is that the system will only store
++ (usually) one copy of the unique contents of each file, regardless of the
++ file's name (it will use extra files if the links overflow the available
++ maximum).
++
++ This patch does not take into account file permissions, extended
++ attributes, or ACLs when linking things together, so you should only use
++ this if you don't care about preserving those extra file attributes (or if
++ they are always the same for identical files).
++
++ The _DIR_ is relative to the destination directory, so either specify a full
++ path to the hash hierarchy, or specify a relative path that puts the links
++ outside the destination (e.g. "../links").
++
++ Keep in mind that the hierarchy is never pruned, so if you need to reclaim
++ space, you should remove any files that have just one link (since they are
++ not linked into any destination dirs anymore):
++
++ > find $DIR -links 1 -delete
++
++ The link farm's directory hierarchy is determined by the file's (32-char)
++ MD5 hash and the file-length. The hash is split up into directory shards.
++ For example, if a file is 54321 bytes long, it could be stored like this:
++
++ > $DIR/123/456/789/01234567890123456789012.54321.0
++
++ Note that the directory layout in this patch was modified for version
++ 3.1.0, so anyone using an older version of this patch should move their
++ existing link hierarchy out of the way and then use the newer rsync to copy
++ the saved hierarchy into its new layout. Assuming that no files have
++ overflowed their link limits, this would work:
++
++ > mv $DIR $DIR.old
++ > rsync -aiv --link-by-hash=$DIR $DIR.old/ $DIR.tmp/
++ > rm -rf $DIR.tmp
++ > rm -rf $DIR.old
++
++ If some of your files are at their link limit, you'd be better of using a
++ script to calculate the md5 sum of each file in the hierarchy and move it
++ to its new location.
