mkisofs and option -graft-points

Hi:
Has that option any effect when no argument of the form path1=path2 is in the command line? If I understand the manual, the option is useless when used in that fashion. But I have seen it used with equal sign nowhere in the invocation command line. Thanks in advance.

Hello friend
Please explain your question , i am unable to understand for what you are asking
Thanks
Rahul

Thanks for your reply. Consider
(a) mkisofs -graft-points <more options> -o image.iso \ CHESS_BOOKS/=/cs/chesstorrent
(b) mkisofs -graft-points <more options> -o image.iso ./con45

In (a) -graft-points makes sense, because of 'CHESS_BOOKS/=/cs/chesstorrent'. In (b), on the contrary, I see no point in using -graft-points. This is my humble opinion. From mkisofs manual:

Quote:

-graft-points
Allow to use graft points for filenames. If this option is used,
all filenames are checked for graft points. The filename is
divided at the first unescaped equal sign. All occurrences of
'\\' and '=' characters must be escaped with '\\' if
-graft-points has been specified.
