rsync - Feb 2005 - Rsync Include confusion

I am trying to understand the include/exclude functions of rsync...what I
want to do is have a folder with appended files...such as thisfile.gif.bak
I want rsync to include ALL *.*.bak files and skip over everything
else...But thisfile.gif exist in the same folder as thisfile.gif.bak
Can I exlude using a wild card like *.gif...???
