Good point, i forgot the remove case all together.

The infodir trigger would be:

rm /usr/share/info/dir
find /usr/share/info -type f -iname *.info* \
  -exec install-info '{}' /usr/share/info/dir 2>/dev/null

As there is no distinct add or remove of pages possible if the trigger 
runs after the transaction has finished. During transaction addition and 
removal of info-pages could have happened. So we would need to build the 
index new every time. Not very clean but works fast enough even an an 
old P3 750mhz here.

Take a look at man makepkg.conf and search for zipman. What makepkg 
doesn't do is to extract compressed files in the !zipman case.
