   7 # All questions should have been asked via debconf
   8 # now we just go get those, build a temp file which we read in and
   9 # then build our config files and set everthing up

  13 # summary of how this script can be called:
  14 #        * <postinst> `configure' <most-recently-configured-version>
  15 #        * <old-postinst> `abort-upgrade' <new version>
  16 #        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
  17 #          <new-version>
  18 #        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
  19 #          <failed-install-package> <version> `removing'
  20 #          <conflicting-package> <version>
  21 # for details, see /usr/share/doc/packaging-manual/
  22 #
  23 # quoting from the policy:
  24 #     Any necessary prompting should almost always be confined to the
  25 #     post-installation script, and should be protected with a conditional
  26 #     so that unnecessary prompting doesn't happen if a package's
  27 #     installation fails and the `postinst' is called with `abort-upgrade',
  28 #     `abort-remove' or `abort-deconfigure'.
