  Additional material may be included in the generated output with the
  .B \-\-include
  and
  .B \-\-opt\-include
  options.  The format is simple:
  
      [section]
      text
  
      /pattern/
      text
  EOT
  print OUT "\n";
  
  print OUT _(<<'EOT');
  Blocks of verbatim *roff text are inserted into the output either at
  the start of the given
  .BI [ section ]
  (case insensitive), or after a paragraph matching
  .BI / pattern /\fR.
  EOT
  print OUT "\n";
  
  print OUT _(<<'EOT');
  Patterns use the Perl regular expression syntax and may be followed by
  the
  .IR i ,
  .I s
  or
  .I m
  modifiers (see
  .BR perlre (1)).
  EOT
  print OUT "\n";
  
  print OUT _(<<'EOT');
  Lines before the first section or pattern which begin with `\-' are
  processed as options.  Anything else is silently ignored and may be
  used for comments, RCS keywords and the like.

  Any
  .B [NAME]
  or
  .B [SYNOPSIS]
  sections appearing in the include file will replace what would have
  automatically been produced (although you can still override the
  former with
  .B --name
  if required).
  EOT
  print OUT "\n";

  Other sections are prepended to the automatically produced output for
  the standard sections given above, or included at
  .I other
  (above) in the order they were encountered in the include file.
