#
# ---- Configuring a speech server using debconf ----
#
# A package can contribute several speech servers, as follows.
#
#
# Use the method described in debconf-devel(7) "choosing among related
# packages" to detect a new package. All packages installing speech
# servers include the same template file. A fake question
# "shared/emacspeak/fake" is shared by all the packages. Each package
# contributes its name as a "choice". The question is "fake" because
# the it is never displayed to a user. Instead, if the package list
# changes, use fset to declare a *different* question as not seen:
# "shared/emacspeak/device". That question has the real speech server
# choices. A new package contributes all the relevant choices to all
# questions, and a package being removed removes its choices (in
# prerm).
