updating man.conf

[Siju George]

Hi,

while updating packages i found the below instruction

--- qt3-mt-3.8p2 -------------------
You may wish to add /usr/local/lib/qt3/man to /etc/man.conf
--- samba-3.0.33 -------------------

what is the exact line I should add to man.conf and where should i add it?
Is there anything else I should do after adding the line to man.conf
to view the man page

thanks
