@settitle: Set the Document Title
A Texinfo file should contain a line that looks like this:
@settitle command at the beginning of a line and
follow it on the same line by the title. Do not write anything else
on the line. The
@settitle command should precede everything
that generates actual output. The best place for it is right after
@setfilename command (described in the previous section).
This command tells TeX the title to use in a header or footer for double-sided output, in case such headings are output. For more on headings for TeX, see Heading Generation.
In the HTML file produced by
makeinfo, title serves as
the document ‘<title>’. It also becomes the default document
description in the ‘<head>’ part
When the title page is used in the output, the title in the
@settitle command does not affect the title as it appears on
the title page. Thus, the two do not need not match exactly. A
practice we recommend is to include the version or edition number of
the manual in the
@settitle title; on the title page, the
version number generally appears as an
@subtitle so it would
be omitted from the
@title. See @titlepage.
