 `@value' Example
 ----------------
 
   You can use the `@value' command to minimize the number of places you
 need to change when you record an update to a manual.   GNU Sample
 Texts, for an example of this same principle can work with Automake
 distributions, and full texts.
 
 
   1. Set the flags:
 
           @set EDITION 0.35 Beta
           @set VERSION 3.63 Beta
           @set UPDATED 14 August 1992
           @set UPDATE-MONTH August 1992
 
   2. Write text for the `@copying' section ( copying):
 
           @copying
           This is Edition @value{EDITION},
           last updated @value{UPDATED},
           of @cite{The GNU Make Manual},
           for @code{make}, version @value{VERSION}.
           
           Copyright ...
           
           Permission is granted ...
           @end copying
 
   3. Write text for the title page, for people reading the printed
      manual:
 
           @titlepage
           @title GNU Make
           @subtitle A Program for Directing Recompilation
           @subtitle Edition @value{EDITION}, ...
           @subtitle @value{UPDATE-MONTH}
           @page
           @insertcopying
           ...
           @end titlepage
 
      (On a printed cover, a date listing the month and the year looks
      less fussy than a date listing the day as well as the month and
      year.)
 
   4. Write text for the Top node, for people reading the Info file:
 
           @ifnottex
           @node Top
           @top Make
           
           @insertcopying
           ...
           @end ifnottex
 
      After you format the manual, the `@value' constructs have been
      expanded, so the output contains text like this:
 
           This is Edition 0.35 Beta, last updated 14 August 1992,
           of `The GNU Make Manual', for `make', Version 3.63 Beta.
 
   When you update the manual, you change only the values of the flags;
 you do not need to edit the three sections.
