One other note regarding use of apt-get in a script or invoked at CL,
you should not need a separate line for each program... space
separated works good as far as I know.

> apt-get -y install synaptic mysql-client-core-5.1 mysql-cluster-client-5.1

works just as well as

> apt-get install synaptic
> apt-get install mysql-client-core-5.1
> apt-get install mysql-cluster-client-5.1
