NAME
     postreverse - reverse the page order in a PostScript file

SYNOPSIS
     postreverse [-o list] [-r] [file]


     /usr/lib/lp/postscript/postreverse


DESCRIPTION
     The postreverse filter reverses the page order in files that
     conform to Adobe's Version 1.0 or Version 2.0 file structur-
     ing conventions, and writes the results on the standard out-
     put. Only one input file is allowed and if no file is speci-
     fied, the standard input is read.


     The postreverse filter can handle a limited class  of  files
     that  violate page independence, provided all global defini-
     tions are bracketed by %%BeginGlobal  and  %%EndGlobal  com-
     ments.  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 was not.

OPTIONS
     -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. The page range is an expression of logi-
                cal  pages  rather than physical sheets of paper.
                For example, if  you  are  printing  two  logical
                pages to a sheet, and you specified a range of 4,
                then two sheets of paper would print,  containing
                four  page layouts. If you specified a page range
                of 3-4, when requesting two logical  pages  to  a
                sheet;  then only page 3 and page 4 layouts would
                print, and they  would  appear  on  one  physical
                sheet of paper.


     -r         Do not reverse the pages in file.

EXAMPLES
     Example 1 Examples of postreverse.


     o select pages 1 to 100 from file and reverse the pages:


       example% postreverse -o1-100 file




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


       example% postprint -n4 file  postreverse




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


       example% dpost file  postreverse -r

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