How to make a slippy map of tunisia

Hi all,
I am interested to use mapnik to have a slippy map of Tunisia.
I have put the data in postgris , and i obtained this tables :
**) tunisia_administrative
**) tunisia_coastline
**) tunisia_highway
**) tunisia_natural
**) tunisia_poi
i am asking about the next step, because the manuel : “How to make a local open street map speak about a world map”, i didn’t found the solution to make the same initiative to make tunisia map.
