[help-texinfo] adding <link rel="canonical" ...>

[Marc Glisse]

Hello,

I am looking for a way to add <link rel="canonical" href="somewhere/$file" 
/> to the headers of the generated html pages. With makeinfo, it doesn't 
seem possible :-(

So I looked at texi2html (with --node-files to get a similar result), 
there is $EXTRA_HEAD, but I couldn't see how to reference the file name 
from there (I am not a perl guru).

For now I am using a postprocessing script that inserts the line before 
</head>, but if texinfo could do it for me...
