[NTG-context] document links in the wiki

Hi, on the page http://wiki.contextgarden.net/ConTeXt_an_Excursion%2C_translations there are some broken links, such as: https://foundry.supelec.fr/docman/view.php/22/15/ma-cb-nl-screen.pdf does anyone know where to find these files? Or are they gone? Patrick
