automatically pier page detection

Hi folks. I am creating a website where I have countries, states, places, cities and so on. I have several pages talking about that. And I want to put internal links everywhere they are called in a Pier page. Example. Suppose I have this piece of text in a Pier page: "I hope Brest to be a nice city. It is situated in France, far away from Paris." In my website I have another page called "France" and another called "Paris". So, I would like the text above to be: "I hope Brest to be a nice city. It is situated in *France*, far away from *Paris*." But I have a lot of pages and places. Is there a way this to be detected easier? I ask because in some wiki I saw this behaviour. Thanks in advance, Mariano
