   9 #        * <postinst> `configure' <most-recently-configured-version>
  10 #        * <old-postinst> `abort-upgrade' <new version>
  11 #        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
  12 #          <new-version>
  13 #        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
  14 #          <failed-install-package> <version> `removing'
  15 #          <conflicting-package> <version>
  16 # for details, see http://www.debian.org/doc/debian-policy/ or
  17 # the debian-policy package
  18 #
  19 # quoting from the policy:
  20 #     Any necessary prompting should almost always be confined to the
  21 #     post-installation script, and should be protected with a conditional
  22 #     so that unnecessary prompting doesn't happen if a package's
  23 #     installation fails and the `postinst' is called with `abort-upgrade',
  24 #     `abort-remove' or `abort-deconfigure'.
