[gl2ps] gl2ps - two questions

[Ian D. Gay]

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?
