The file input shall be a file in postscript, formatted using the etendu format of Linköping University Electronic Press. The page number input shall be a non-negative integer, less than 1000, and the sum of that number and the number of pages in the file must also be less than 1000.
The output file is a modification of the input file where the first three pages (front page, copyright information, etc) have been removed, and the following pages have been renumbered starting with the number given as argument.
The program will only change the page numbers marking the pages; it does not (of course) change cross-references made by page number within the text itself. Anyway, the fact that this transformation was easily implemented suggests that with moderate precautions, we should be able to go automatically from individual articles with page numbering from 1 and up, to journal issues composed of a number of articles and with consecutive page numbering.
