`@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.  Here is how it
is done in `The GNU Make Manual':

  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 first `@ifinfo' section, for people reading the
     Texinfo file:

          This is Edition @value{EDITION},
          last updated @value{UPDATED},
          of @cite{The GNU Make Manual},
          for @code{make}, version @value{VERSION}.

  3. Write text for the title page, for people reading the printed
     manual:

          @title GNU Make
          @subtitle A Program for Directing Recompilation
          @subtitle Edition @value{EDITION}, ...
          @subtitle @value{UPDATE-MONTH}

     (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:

          This is Edition @value{EDITION}
          of the @cite{GNU Make Manual},
          last updated @value{UPDATED}
          for @code{make} Version @value{VERSION}.

     After you format the manual, the text in the first `@ifinfo'
     section looks 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, change only the values of the flags; you
do not need to edit the three sections.
