     1  UNMODIFIED BINARY DISTRIBUTION LICENCE
     2  
     3  
     4  PREAMBLE
     5  
     6  The GNU General Public License provides a legal guarantee that
     7  software covered by it remains free (in the sense of freedom, not
     8  price).  It achieves this guarantee by imposing obligations on anyone
     9  who chooses to distribute the software.
    10  
    11  Some of these obligations may be seen as unnecessarily burdensome.  In
    12  particular, when the source code for the software is already publicly
    13  and freely available, there is minimal value in imposing upon each
    14  distributor the obligation to provide the complete source code (or an
    15  equivalent written offer to provide the complete source code).
    16  
    17  This Licence allows for the distribution of unmodified binaries built
    18  from publicly available source code, without imposing the obligations
    19  of the GNU General Public License upon anyone who chooses to
    20  distribute only the unmodified binaries built from that source code.
    21  
    22  The extra permissions granted by this Licence apply only to unmodified
    23  binaries built from source code which has already been made available
    24  to the public in accordance with the terms of the GNU General Public
    25  Licence.  Nothing in this Licence allows for the creation of
    26  closed-source modified versions of the Program.  Any modified versions
    27  of the Program are subject to the usual terms and conditions of the
    28  GNU General Public License.
    29  
    30  
    31  TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    32  
    33  This Licence applies to any Program or other work which contains a
    34  notice placed by the copyright holder saying it may be distributed
    35  under the terms of this Unmodified Binary Distribution Licence.  All
    36  terms used in the text of this Licence are to be interpreted as they
    37  are used in version 2 of the GNU General Public License as published
    38  by the Free Software Foundation.
    39  
    40  If you have made this Program available to the public in both source
    41  code and executable form in accordance with the terms of the GNU
    42  General Public License as published by the Free Software Foundation;
    43  either version 2 of the License, or (at your option) any later
    44  version, then you are hereby granted an additional permission to use,
    45  copy, and distribute the unmodified executable form of this Program
    46  (the "Unmodified Binary") without restriction, including the right to
    47  permit persons to whom the Unmodified Binary is furnished to do
    48  likewise, subject to the following conditions:
    49  
    50  - when started running, the Program must display an announcement which
    51    includes the details of your existing publication of the Program
    52    made in accordance with the terms of the GNU General Public License.
    53    For example, the Program could display the URL of the publicly
    54    available source code from which the Unmodified Binary was built.
    55  
    56  - when exercising your right to grant permissions under this Licence,
    57    you do not need to refer directly to the text of this Licence, but
    58    you may not grant permissions beyond those granted to you by this
    59    Licence.
