From the manpage of rsync (I have thought the - is perl syntax, before):

 o      if  the  pattern  starts  with "+ " (a plus followed by a space) then it is
        always considered an include pattern, even  if  specified  as  part  of  an
        exclude option. The "+ " part is discarded before matching.

 o      if  the  pattern  starts with "- " (a minus followed by a space) then it is
        always considered an exclude pattern, even  if  specified  as  part  of  an
        include option. The "- " part is discarded before matching.

As I understand in an exclude-option you never need a "-" and in an
include-option you never need a "+". (But is does no harm) The exclude
and include options are parsed from the first to the last param and in
the e/i-lists from the first line to the last. The first patern match
is valid, no matter if there is a "+" or "-" sign.

Because Jerome already fixed the woody package, I feel it is good to
wait for his patch and concentrate on repli-update in the meantime.

I will run some deeper tests this afternoon, to find out what files are
exclude during repli-sync and what files not. Do you think it is good
to do a new repli-install before or is it sufficient only to install
the new debian package (CVS from 30.10.2002) on model and target.

I you like that I run a spezial test, watch a spezial behavior or
include a spezial patch before, just write me.

After repli-update is working I think it is good to:
a) write some documentation (e.g. manpages, more clean installation
   instructions) 
b) implement some nice new features (e.g. the @change_hostname list).

Attached you find my "cvs diff" from today.
