text-path for a text

Hi ! I need to add a text with a text-path (because the text must follow a path) . Do you think it's possible ? I search on github, and other website but i find nothing on raphaeljs for this. I try to modify raphael. js, to add my own function which can add a text-path, but I have difficulty to understand the code, because I am novice in SVG / VML. Could You help me? Thanks.
