Hi,
I am trying to pick up on an old thread of creating an overview page [1].
Basically, the idea is to create an overvew slide at the end of a
presentation that shows the first page of different sections in a
presentation. Based on Wolfgang's answer in that old thread, I save the
relevant pages in a box, and then display them again at the end of the
presentation.
This works, except that I get a series of warnings:
l.86 \placeoverviewpage
LuaTeX warning (ext4): destination with the same
identifier (name{aut:10}) has been already used, duplicate ignored
How do I get rid of these?
I am afraid that I cannot create a small example illustrating this
warning, so I am attaching the complete test file.

Tricky. The problem is that you flush a box (copy) so the message comes
from deep inside the backend (for good reason) and so we cannot
intercept it as "hey user, you use the same dest twice" simply because
it's a copy and not re-rendered.
There are two solutions:
(1) strip the box before copying (i can make a helper for that - later
as i have to go now): destinations, references, writes-to-lists etc
(2) you copy the old file before processing and use that one
\def\placeoverviewpage
{\startstandardmakeup[\c!align=\v!middle]
\getfiguredimensions[temp.pdf]%
\dorecurse{\noffigurepages}{\externalfigure[temp.pdf][\c!page=##1,\c!width=\overviewwidth]\relax\space}
\stopstandardmakeup}

[2] It has always been a wish of mine to have it as option in the engine
(pdfetex) but in luatex it's not that hard to do it myself now (i
already have a stripper so I can extend that one a bit).

attached ... you can run the module for an example (you need a new beta)

Thanks, works nicely.
I'll add the configuration commands, and release it as a module.

ok; i already did the commandhandler so it should be easy to extend ..
no problem adding it to the standard distribution (i'll add some
comments then about the 'issue' of duplication) as it can probably serve
some more purposes (and be extended)
