PostScript files

[fonseca at ams.sunysb.edu (Leonardo Ribeiro)]

My name is Fonseca and I am a graduate student here at State University
of New York at Stony Brook. We have been using geomview to generate
3D pictures of organic molecules and it has been an useful tool. But
we would like to generate PS files from the picture we have in the 
screen and it is not clear how to do that, if possible.Is there any fast 
way of doing that?
