# 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>
#        * <postinst> abort-remove
#        * <deconfigured's-postinst> abort-deconfigure in-favour <failed-install-package> <version> \
#				     removing <conflicting-package> <version>
# for details, see /usr/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.
