from Greg Bennett. With assistance from the CFFI list I have managed to run the OpenGL example files in cl-glut-examples.lisp, which makes me very relieved. By reading the example files I can collect quite a bit of information about syntax but I would clearly be better off if I had documentation of a more formal and organised variety. In the materials on cl-opengl which I downloaded I can find only the stub of documentation, for example the .pdf includes a disclaimer and then only chapter headings. I tried to build things from gendocs.sh and managed to create only that same stub. It seems I am missing the text files to fill those chapters. If those are available, I would appreciate a pointer to them. Since I am relatively new to linux it is quite likely that I simply don't (yet) know where to find such things. Thx for any and all advice and assistance. Cheers /Greg Bennett
