or to allow multiple files to be concatenated).  Second choice is the
total number of %%Page lines.

This is how most Postscript utilities determine page counts and/or
split files in to individual pages without needing to interpret the
complete file.

NB Microsoft print drivers don't necessarily produce fully valid DSCs
by default, although they do seem to produce Page and Pages.
