cleaning APT cache in ubuntu 8.04

recently i read in a book as follows

cleaning APT cache

edit /etc/apt/apt.conf.d/10periodic as follows

APT::Periodic:Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "0";
APT::Archives::MaxAge "7";


buit in my /etc/apt/apt.conf.d/10periodic file i am finding only these entries

APT::Periodic::Update-Package-Lists "1";
APT::Periodic:Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";

there is no APT::Archives::MaxAge "7"; should i add it ?

Look in /etc/apt/apt.conf.d/20archive, that is where the

APT::Archives::MaxAge 30

directive is set

I'm using the Intrepid beta mine is set a 30.
