There appear to be dvips options to turn off structured comments but
none to turn them on. In the dvips documentation I came across:

Using `bop-hook' or `eop-hook' to preserve information across pages
breaks compliance with the Adobe document structuring conventions, so
if you use any such tricks, you may also want to use the `-N' option to
turn off structured comments (such as `%%Page').  Otherwise, programs
that read your file will assume its pages are independent.

Looking in the final ps file I found these macros are indeed used. I
would like to investigate further as I believe a lot of GNU/Linux users
do use gv to preview postscript. Does anyone know the anwers to the
following:

1] Where do they come from? (They are not in the fonts.ps file)

2] Are they used to preserve information across pages?

3] If the answer to [2] is "No", why are structured comments turned off?

4] If the answer to [2] is "Yes", is this really necessary?

5] How have structured comments been turned off? - The documentation
implies you need to use the -N or -K options to do this.
