   9 In addition, prior to November 15th, 2000, apt may be distributed under
  10 terms identical to the above with the following addition:
  11
  12 Works using apt may link against the GUI library "libqt", copyright by
  13 Troll Tech AS, Norway, provided that:
  14
  15 1. The version of "libqt" is licensed under the terms of the "Qt Free Edition
  16    License" published by Troll Tech AS.  The license terms identified as
  17    the Qt Free Edition License below are the only such terms under which
  18    distribution of works derived from both apt and "libqt" are permitted;
  19
  20 and
  21
  22 2. The source code of the version of "libqt" used is
  23
  24    a) Distributed with the binary version;
  25
  26    or
  27
  28    b) Downloadable by anyone, without fee, using a publicly-announced
  29       URL on the Internet, for a duration of at least three years
  30       starting with distribution of the binary version.
  31
  32 On and after November 15th, 2000, the above additional terms lose all
  33 force, and apt will be licensed only under the terms of the GNU General
  34 Public License, version 2.0 or later.

  38 The following text, up to the text of the Qt Free Edition License, is
  39 informational and not part of the license terms on apt.
  40
  41 Modifications to apt in either source or compiled form must be licensed
  42 under the terms of the GNU General Public License, version 2.0 (or later),
  43 but need not include the above clause permitting usage of the "libqt"
  44 library under the Qt Free Edition License.  Note that removal of this
  45 clause will result in software which is not licensed for binary
  46 redistribution linked against software governed by the Qt Free Edition
  47 License.  In the event that a version of "libqt" is released that is
  48 licensed under terms that do not conflict with the GPL, the additional
  49 clause above is not required to grant permission for distribution of works
  50 that are derived from both apt and "libqt".
  51
  52 No part of apt is licensed under the Qt Free Edition License.  The terms
  53 below are provided to help identify the circumstances under which the
  54 "libqt" library may be used with apt (or a work derived from both).  The
  55 terms below are copied from the LICENSE file of the qt-1.44 distribution,
  56 as of November 10th, 1999.
