+#        * <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'.
