Some of the documents available here are in PostScript (.ps) format.
To view a PostScript document while in Netscape on the department's Unix system, just click on the link and a "ghostview" window should pop up. To view a PostScript document from a home computer, you may need to download a PostScript viewer such as ghostview. To find ghostview for your operating system and architecture, search for it with a search engine, e.g. the one at www.google.com.
To print a PostScript document on Unix, save it in a temporary file (by, for instance, clicking the right mouse button on the link in Netscape) and print the file normally.
You can also print a PostScript file so that two pages of the document fit onto one physical page. This might come in handy for the course transparencies, which are in big enough font that they are still readable this way. You can do this by issuing the Unix command
Remember to remove temporary files after they have been printed, to save space.
