# postinst script for tpconfig
#
# see: dh_installdeb(1)
set -e
# 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 /usr/share/doc/packaging-manual/
#
# 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'.
