   Yes tramp use ssh-agent, if ssh-agent is started; if not you are prompted 
for a
   passphrase (you have to create keys and use keys system, not password).
   I don't use cvs for my files, i use svn.
   With svn if you do your checkout throught ssh, and ssh-agent+keys system is
   enabled, when you commit the change in your file, svn use automaticly ssh 
with
   tramp.

Do you have any good tuto to set this up ? I am one of these lazy
people who'd rather type their password every two minutes ;)
Ssh-agent could save me some precious time. Lat time I read about
this, it was a pain (for me) to understand.

AFAIK, depending on how one is starting GNU Emacs, the setup
changes. I am mostly working from the linux console, GNU Emacs is
launched through a screen server session which I am connecting
with the help of emacsclient.

I even have a system account which default login shell is
/usr/bin/emacs thus I do not see how ssh-agent could be setup in
this case.
