Texinfo files start with at least three lines that provide Info and
TeX with necessary information. These are the \input texinfo
line, the @settitle
line, and the @setfilename
line.
Also, if you want to format just part of the Texinfo file, you must
write the @settitle
and @setfilename
lines between
start-of-header and end-of-header lines. The start- and end-of-header
lines are optional, but they do no harm, so you might as well always
include them.
Any command that affects document formatting as a whole makes sense to
include in the header. @synindex
(see synindex), for
instance, is another command often included in the header. See GNU Sample Texts, for complete sample texts.
Thus, the beginning of a Texinfo file generally looks like this:
\input texinfo @c -*-texinfo-*- @c %**start of header @setfilename sample.info @settitle Sample Manual 1.0 @c %**end of header
• First Line: | The first line of a Texinfo file. | |
• Start of Header: | Formatting a region requires this. | |
• setfilename: | Tell Info the name of the Info file. | |
• settitle: | Create a title for the printed work. | |
• End of Header: | Formatting a region requires this. |
