16 The postreverse filter reverses the page order in files that conform to
17 Adobe's Version 1.0 or Version 2.0 file structuring conventions, and
18 writes the results on the standard output. Only one input file is
19 allowed and if no file is specified, the standard input is read.

21
22 The postreverse filter can handle a limited class of files that violate
23 page independence, provided all global definitions are bracketed by
24 %%BeginGlobal and %%EndGlobal comments. In addition, files that mark
25 the end of each page with %%EndPage: label ordinal comments will also
26 reverse properly, provided the prologue and trailer sections can be
27 located. If postreverse fails to find an %%EndProlog or %%EndSetup com‐
28 ment, the entire file is copied, unmodified, to the standard output.

31 Because global definitions are extracted from individual pages and put
32 in the prologue, the output file can be minimally conforming, even if
33 the input file was not.
34
36 -o list Select pages whose numbers are given in the comma-separated
37 list. The list contains single numbers N and ranges N1 − N2.
38 A missing N1 means the lowest numbered page, a missing N2
39 means the highest. The page range is an expression of logi‐
40 cal pages rather than physical sheets of paper. For example,
41 if you are printing two logical pages to a sheet, and you
42 specified a range of 4, then two sheets of paper would
43 print, containing four page layouts. If you specified a page
44 range of 3-4, when requesting two logical pages to a sheet;
45 then only page 3 and page 4 layouts would print, and they
46 would appear on one physical sheet of paper.

48
49 -r Do not reverse the pages in file.

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