[Pharo-dev] Where did Nativeboost Documentation disappear ?

I am trying to figure out Nativeboost for using dlerror() and I can find the documentation that used to be here https://gforge.inria.fr/scm/viewvc.php/PharoByExampleTwo-Eng/?root=pharobook... it used to be in pbe2 folder and then move there and then it was removed, or way moved somewhere i cant find it. Why ? Can you please bring the pdf back and link to it in the Nativeboost google code website ?
