这是一个同样来自贝尔实验室的和UNIX有着渊源的操作系统, 其简洁的设计和实现易于我们学习和理解

A simple program that reverses the pages in PostScript files that
conform to Adobe's Version 1.0 or Version 2.0 file structuring
conventions.

postrevese also handles a small class of files that violate page
independence (eg. output from dpost) and can be used with all the
translators in this package. The output can be conforming even if
the input file wasn't.
