NAME
     postreverse - reverse the page order in a PostScript file

SYNOPSIS
     /usr/lib/lp/postscript/postreverse [options] [files]

DESCRIPTION
     postreverse 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 to standard output. Only one input file is allowed and if
     no file is specified, standard input is read.

OPTIONS
     -olist Selects 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.

     -Tdir  Uses dir as the temporary file directory when reading from
            standard input. By default dir is set to /tmp.

     postreverse 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 standard output.

     Since global definitions are pulled out of individual pages and put in
     the prologue, the output file can be minimally conforming, even if the
     input file wasn't.

EXAMPLES
     Select pages 1 to 100 from file and reverse the pages,

          postreverse -o1-100 file

     Print 4 logical pages on each physical page and reverse all the pages,

          postprint -n4 file | postreverse

     Produce a minimally conforming file from output generated by dpost
     without reversing the pages,

          dpost file | postreverse -r

DIAGNOSTICS
     0 exit status is returned if files were successfully processed.

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