All,

I've been trying to find the Best Way to update index.html automatically
from Changes/index.list and gallery/events.list while at the same time
updating the translations websites *without* overwriting all existing
(translated) news-entries on those index-pages.

The problem is that we have to make a choice:

(I) We always want to have the latest news on all index pages.  If that
means that the news entries are in english even on the non-english
sites, so be it.  At the same time, we also want to be able to
re-generate the Changes/index.html file (possibly to correct spelling
errors in the headlines) and automatically correct the entries on the
various main pages.

(II) We only want to add the latest News entries to the various main
pages, preserving possibly already translated entries.  This means that
if we encounter a spelling error in the headline and re-generate the
news-entries, we'd end up with two entries for the same news:  they
differ, and so they are treated as separate entries.  (Alternate
scenario:  the headline with the error remains, but no duplicates are
generated)

Solution (I) is what we have in place, and the only problem with this is
that for the translated news, the translators need to regenerate the
entries by hand and paste them into the main page after an update to not
loose the translated links.

Solution (II) is what is attached in a different version of makeindex.sh
and Makefile.

As I write this, I believe it became obvious to me that we want to stick
with (I) and translators have to deal with it.  But if you have other
input (or even a third, better solution), let's discuss it.
