The new2gif program converts PostScript files into GIF files.
Don Middleton wrote it.  It's on magic in /usr/local/bin/new2gif.
There's no man page, but doing a "new2gif -h" will display the command
line options.  To convert a file named petesplace.ps into a GIF file
named petesplace.gif, you'd use this command:

new2gif -p -g850x1100 -opetesplace.gif petesplace.ps
