1. Make sure build-essential is installed (you only need dpkg-dev but...)
2. Copy the deb files in /var/cache/apt/archives to a folder of your choice
3. cd into that folder and do:
	sudo dpkg-scanpackages . /dev/null | gizp -9c > Packages.gz
4. On the new system, edit /etc/apt/sources.list and include something close 
to this:
	deb file:<backed_up_apt_folder>/ /
So if the downloaded deb packages are in /home/robert/repo, the line will look 
like
	deb file:/home/robert/repo/ /
5. Update the package index like so:
	sudo apttitude update
6 Remember to repeat #3 evrytime new debs are added to the repo folder
