`@set', `@clear', and `@value'
==============================

  You can direct the Texinfo formatting commands to format or ignore
parts of a Texinfo file with the `@set', `@clear', `@ifset', and
`@ifclear' commands.

  In addition, you can use the `@set FLAG' command to set the value of
FLAG to a string of characters; and use `@value{FLAG}' to insert that
string.  You can use `@set', for example, to set a date and use
`@value' to insert the date in several places in the Texinfo file.
