Generally, the beginning of a Texinfo file has four parts:

1. The header, delimited by special comment lines, that includes the commands for naming the Texinfo file and telling TeX what definitions' file to use when processing the Texinfo file.
2. A short statement of what the file is about, with a copyright notice and copying permissions. This is enclosed in @ifinfo and @end ifinfo commands so that the formatters place it only in the Info file.
3. A title page and copyright page, with a copyright notice and copying permissions. This is enclosed between @titlepage and @end titlepage commands. The title and copyright page appear only in the printed manual.
4. The `Top' node that contains a menu for the whole Info file. The contents of this node appear only in the Info file.

Also, optionally, you may include the copying conditions for a program and a warranty disclaimer. The copying section will be followed by an introduction or else by the first chapter of the manual.

Since the copyright notice and copying permissions for the Texinfo document (in contrast to the copying permissions for a program) are in parts that appear only in the Info file or only in the printed manual, this information must be given twice.
