Google gave an example http://googlemapsapi.blogspot.com/2007/05/driving-directions-support-added-to.html
Is the source code available somewhere or a tutorial on that precise example ?

Here's a very basic example using the v3 API:

<script type="text/javascript">
var directionsService = new google.maps.DirectionsService();
var directionsDisplay = new google.maps.DirectionsRenderer();
var map = new google.maps.Map(document.getElementById('map'), {
zoom:7,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById('panel'));
var request = {
origin: 'Chicago',
destination: 'New York',
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
