Configures various APT components on Debian-like systems.

The default recipe runs apt-get update during the Compile Phase of the Chef run to ensure that the system's package cache is updated with the latest. It is recommended that this recipe appear first in a node's run list (directly or through a role) to ensure that when installing packages, Chef will be able to download the latest version available on the remote APT repository.

This recipe also sets up a local cache directory for preseeding packages.

Installs the apt-cacher package and service so the system can be an APT cache.

Installs the apt-proxy package and service so the system can be an APT proxy.

Put recipe[apt] first in the run list. If you have other recipes that you want to use to configure how apt behaves, like new sources, notify the execute resource to run, e.g.:

	template "/etc/apt/sources.list.d/my_apt_sources.list" do
	  notifies :run, resources(:execute => "apt-get update"), :immediately
	end

The above will run during execution phase since it is a normal template resource, and should appear before other package resources that need the sources in the template.
