Similarly, here's a UNIX script we use that puts a word across every
page in a PostScript file.  The word is placed diagonally across the
page in outline letters, not gray.  The default word is "DRAFT," but
you can pass it about any word.  I've used "BETA," "FINAL," etc. as
the situation required.  The format of the command is:

        psdraft [-s draftstring] file.ps
