@settitleIn order to be made into a printed manual, a Texinfo file must contain a line that looks like this:
@settitle title
Write the @settitle command at the beginning of a line and
follow it on the same line by the title. This tells TeX the title
to use in a header or footer. Do not write anything else on the line;
anything on the line after the command is considered part of the
title, including a comment.
Conventionally, when TeX formats a Texinfo file for double-sided
output, the title is printed in the left-hand (even-numbered) page
headings and the current chapter title is printed in the right-hand
(odd-numbered) page headings. (TeX learns the title of each chapter
from each @chapter command.) Page footers are not
printed.
Even if you are printing in a single-sided style, TeX looks for an
@settitle command line, in case you include the manual title
in the heading.
The @settitle command should precede everything that generates
actual output in TeX.
Although the title in the @settitle command is usually the
same as the title on the title page, it does not affect the title as
it appears on the title page. Thus, the two do not need not match
exactly; and the title in the @settitle command can be a
shortened or expanded version of the title as it appears on the title
page. (See section @titlepage.)
TeX prints page headings only for that text that comes after the
@end titlepage command in the Texinfo file, or that comes
after an @headings command that turns on headings.
(See section The @headings Command, for more
information.)
You may, if you wish, create your own, customized headings and footings. See section Page Headings, for a detailed discussion of this process.
