How to rsync and exclude hidden files?

[joe at actionline.com]

Thanks to the always excellent help and advice from my plug friends,
I've been able to use 'rsync' to copy files between my Linux boxes,
and it has been a tremendous help.

However, from studying the man page, I can't figure out what the
syntax should be to exclude hidden files. When I use this:

rsync -avH --progress /home/joe/ joe at 192.168.0.73:/home/joe/

It copied all the hidden files and kind of messed up my laptop.

How can I modify that command to exclude hidden files?
