i need to compare two directory trees - old and new, both holds files,<br>
binaries, special files, symbolic and hard links. and create a patch<br>
file<br>
<br>
than, on another system which has a copy of the old dir tree (and<br>
possible some modifications), i need to patch it to make it a 'new'<br>
<br>
what i would like to have is somthing like rsync, which can create a<br>
diff file ...<br>
