html manual links



Hi,
I am making html links into the maxima manual from
another document. they look like this:

manual_path/maxima_5.html#IDX97

But if the manual changes (say adding a chapter or function)
then a lot of links can break. I wonder if there is a way
to avoid this, or is it just a feature of texinfo or
latex2html that can't be avoided.

thanks,
John
