When I wrote my mail about using a debconf question in the metapackage
I've thight about something like putting a configurable variable into


which contains lines like


and use something like

test -f /etc/default/screenreader && . /etc/default/screenreader

if [ "$SCREENREADER_A" = "yes" ] ; then

(or something a bit more sophisticated, but you see the principle).

That should be quite easy to implement because all relevant screenreader
packages are under control of the Debian Accessibility team and this
change could be implemented quite easily.

Kind regards
