awk is easier than perl.  As Stewart pointed out a simple

    -1 1 scale
    595 neg 0 translate

will do.  This works if inserted at the beginning of the definition of
BP in the PostScript.  An awk command to do this is

    awk '{print} /^\/BP{/ { print "-1 1 scale 595 neg 0 translate" }' \
        <file.ps >mirror.ps
