# This script is called as the last step of the installation of the
# package.  All the package's files are in place, dpkg has already done
# its automatic conffile handling, and all the packages we depend of
# are already fully installed and configured.
# summary of how this script can be called:
#        * <postinst> `configure' <most-recently-configured-version>
#        * <old-postinst> `abort-upgrade' <new version>
#        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
#          <new-version>
#        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
#          <failed-install-package> <version> `removing'
#          <conflicting-package> <version>
# for details, see http://www.debian.org/doc/debian-policy/ or
# the debian-policy package
#
# quoting from the policy:
#     Any necessary prompting should almost always be confined to the
#     post-installation script, and should be protected with a conditional
#     so that unnecessary prompting doesn't happen if a package's
#     installation fails and the `postinst' is called with `abort-upgrade',
#     `abort-remove' or `abort-deconfigure'.

# The following idempotent stuff doesn't generally need protecting
# against being run in the abort-* cases.

# Install info files into the dir file
# install-info --quiet --section "section pattern" "Section Title" \
#              --description="Name of the document" /usr/info/${package_name}.info

# Create stub directories under /usr/local
#  if test ! -d /usr/local/lib/${package_name}; then
#    if test ! -d /usr/local/lib; then
#      if mkdir /usr/local/lib; then
#        chown root.staff /usr/local/lib || true
#        chmod 2775 /usr/local/lib || true
#      fi
#    fi
#    if mkdir /usr/local/lib/${package_name}; then
#      chown root.staff /usr/local/lib/${package_name} || true
#      chmod 2775 /usr/local/lib/${package_name} || true
#    fi
# fi

# Ensure the menu system is updated
# [ ! -x /usr/bin/update-menus ] || /usr/bin/update-menus

# Arrange for a daemon to be started at system boot time

    ### We could also do this on the fly. The following is from Tore
    ### Anderson:

    # This package uses debconf to ask a question, so source the debconf
    # confmodule as early as possible. However, it does not depend on debconf,
    # so debconf may not be installed.
    if [ -e /usr/share/debconf/confmodule ]; then
        . /usr/share/debconf/confmodule
        db_capb
    fi


    ### find out what the user answered.
    #  db_get foo/run_on_boot
    #  run_on_boot=$RET
    #  db_stop

    ### safely create a temporary file to generate our suggested
    ### configuration file.
    #    tempfile=`tempfile`
    #    cat << _eof > $tempfile
    ### Configuration file for Foo.

    ### this was answered by you, the user in a debconf dialogue
    #  RUNONBOOT=$run_on_boot

    ### this was not, as it has a sane default value.
    #  COLOUROFSKY=blue

    #_eof

    ### Note that some versions of debconf do not release stdin, so
    ### the following invocation of ucf may not work, since the stdin
    ### is never coneected to ucfr.

    ### now, invoke ucf, which will take care of the rest, and ask
    ### the user if he wants to update his file, if it is modified.
    #ucf $tempfile /etc/foo.conf

    ### done! now we'll just clear up our cruft.
    #rm -f $tempfile
