`@setfilename': Set the output file name
----------------------------------------
In order to serve as the primary input file for either `makeinfo' or
TeX, a Texinfo file must contain a line that looks like this:
@setfilename INFO-FILE-NAME
Write the `@setfilename' command at the beginning of a line and
follow it on the same line by the Info file name. Do not write anything
else on the line; anything on the line after the command is considered
part of the file name, including what would otherwise be a comment.
The Info formatting commands ignore everything written before the
`@setfilename' line, which is why the very first line of the file (the
`\input' line) does not show up in the output.
The `@setfilename' line specifies the name of the output file to be
generated. This name must be different from the name of the Texinfo
file. There are two conventions for choosing the name: you can either
remove the extension (such as `.texi') entirely from the input file
name, or, preferably, replace it with the `.info' extension.
Although an explicit `.info' extension is preferable, some operating
systems cannot handle long file names. You can run into a problem even
when the file name you specify is itself short enough. This occurs
because the Info formatters split a long Info file into short indirect
subfiles, and name them by appending `-1', `-2', ..., `-10', `-11', and
so on, to the original file name. ( Tag and Split Files.) The
subfile name `texinfo.info-10', for example, is too long for old
systems with a 14-character limit on filenames; so the Info file name
for this document is `texinfo' rather than `texinfo.info'. When
`makeinfo' is running on operating systems such as MS-DOS which impose
severe limits on file names, it may remove some characters from the
original file name to leave enough space for the subfile suffix, thus
producing files named `texin-10', `gcc.i12', etc.
When producing HTML output, `makeinfo' will replace any extension
with `html', or add `.html' if the given name has no extension.
The `@setfilename' line produces no output when you typeset a manual
with TeX, but it is nevertheless essential: it opens the index,
cross-reference, and other auxiliary files used by Texinfo, and also
reads `texinfo.cnf' if that file is present on your system (
