Two unrelated questions - 1. What is the purpose of the filename argument to gl2psBeginPage? It doesn't seem to be used for anything. 2. I have been using SWIG to wrap gl2ps into a tcl package to use alongside Paul Obermeier's tclogl package. I would like to distribute my package to the tcl community for free usage. Does the gl2ps license permit this? If so, what exactly should I distribute? Ian
