It's nice to insert a copyright string at the bottom of the first page
of a PostScript file you put up on the web. People who
download it will be more likely to get the citation right, plus
it does placate the publishers. It's very
straightforward:
open up your file in vi (which handles huge files more
quickly than emacs)
type "/Page: 1 1" to find the start of the first page
directly after that line insert a block like the
following, changing the text in parentheses to the correct string:
gsave
