Hi!
You might already know this, but
https://www.gnu.org/software/gnulib/manual/html_node/index.html shows the
documentation of the ‘index’ module at its bottom. It smells like a problem in
makeinfo. The page was used with Texinfo 6.3. I tried to reproduce it with
Texinfo 6.5, but then the index.html I get is really the index, not the front
page of the documentation.
I had run
$ make updated-stamp
$ ../build-aux/gendocs.sh \
-I ../build-aux \
--email [email protected] \
-o "/tmp/manual" \
gnulib "The GNU Portability Library"
Cheers!
