Texinfo and text file generation.

I have some difficulties to build a text file as clean as a pdf file or html file 

(In the pdf-file  there is no clickable link in the index) .

I have tried several methods (texi2any (GNU texinfo) 6.7 fedora 34)

:

%.txt: %.tex

makeinfo  --no-header -D'TXT 1' --no-split -o$*.txt  $<

%.txt2: %.tex

makeinfo  -D'TXT 1' --plaintext --no-split -o$*.txt2  $<

I couldn't find a simple and clean way to:

• get the title.
• get the copyright and author.
• suppress a menu entry that shows up in the index.
• get the title : "table of contents" along with the content.

Probably, I will have to extensively use the TXT variable to complete my text file.

the tex source file: 

\input texinfo @c -*-texinfo-*-
@set title chess-ec-4.2.2
@set subtitle  Manuel d'utilisation 1.0
@set author Marc Dechico
@c %**start of header
@setfilename chess-ec_fr.info
@documentlanguage fr_FR
@settitle  Manuel d'utilisation 1.0 pour chess-ec-4.2.2
@c %**end of header
