Hello,

I ask me about the relevance of this warning.
If the option has been set twice, where is the problem ?

Or something might miss my knowledge...

Thanks in advance

What is unclear about the warning?

I don't know, a warning is a warning: something might be wrong, or
might go bad, but TeX can compile either. May be this warning has such
a significance, may be that's just like "You required twice the package
hyperref, once would be enough" - Hmm... ok I don't care, than an info
could be enough as well. So many warnings with LaTeX fonts and
over/under full boxes yet !

What do you think ?

Exactly.

No, LaTeX package system allows this. The first time the package
is loaded. LaTeX only complains, if a option is given in later
requests and the package was loaded without that option.

Definitely no. The invokation of the option that causes the
warning was done too late. The code that requests this option
is therefore wrong and even an error message is justified.

Well you're right. But I don't understand:
holtxdoc loads hypdoc which loads hyperref with option
hyperindex=false.

Nevertheless, the index is clickable... ???

Yours sincerely.

That doesn't generate the warning.

`hypdoc' implements its own index linking stuff adapted to
package `doc'.
