Info Format: A Whole Manual
---------------------------

To begin, an Info manual is either "nonsplit" (contained wholly within a
single file) or "split" (across several files).

  The syntax for a nonsplit manual is:

         <nonsplit info file> =
     <preamble>
     <node>*
     <tag table>
     (<local variables>)?

  When split, there is a "main file", which contains only pointers to
the nodes given in other "subfiles".  The main file looks like this:

         <split info main file> =
     <preamble>
     <indirect table>
     <tag table>
     (<local variables>)?

  The subfiles in a split manual have the following syntax:

         <split info subfile> =
     <preamble>
     <node>*
