Lecture notes will be available in either postscript or pdf format.
For files that are in postscript format, you need
a postscript previewer. You should be able to view them on the SparcStations.
If you want to print them, while viewing them, select "save" and save
as a file with a ".ps" extension, for example: lect1.ps
You can then send the file to the printer by typing: lpr lect1.ps
