   NAME
         postreverse - reverse the page order in a PostScript file

   SYNOPSIS
         postreverse [options] [file]

   DESCRIPTION
         The postreverse filter reverses the page order in files that conform
         to Adobe's Version 1.0 or Version 2.0 file structuring conventions,
         and writes the results on the standard output.  Only one input file
         is allowed and if no file is specified, the standard input is read.
         The following options are understood:

         -o list   Select pages whose numbers are given in the comma-separated
                   list.  The list contains single numbers N and ranges N1 -
                   N2.  A missing N1 means the lowest numbered page, a missing
                   N2 means the highest.

         -r        Don't reverse the pages in file.

         The postreverse filter can handle a limited class of files that
         violate page independence, provided all global definitions are
         bracketed by %%BeginGlobal and %%EndGlobal comments.  In addition,
         files that mark the end of each page with %%EndPage: label ordinal
         comments will also reverse properly, provided the prologue and
         trailer sections can be located.  If postreverse fails to find an
         %%EndProlog or %%EndSetup comment, the entire file is copied,
         unmodified, to the standard output.

         Because global definitions are extracted from individual pages and
         put in the prologue, the output file can be minimally conforming,
         even if the input file wasn't.

   EXAMPLES
         To select pages 1 to 100 from file and reverse the pages:

               postreverse -o1-100 file

         To print four logical pages on each physical page and reverse all the
         pages:

               postprint -n4 file | postreverse

         To produce a minimally conforming file from output generated by dpost
         without reversing the pages:

               dpost file | postreverse -r

   DIAGNOSTICS
         An exit status of 0 is returned if file was successfully processed.

   NOTES
         No attempt has been made to deal with redefinitions of global
         variables or procedures.  If standard input is used, the input file
         will be read three times before being reversed.
