   7 Preamble
   8 --------
   9
  10 This licence is intended to protect wxWindows, its developers,
  11 and its users, so that the considerable investment it represents
  12 is not abused.
  13
  14 Unlike the L-GPL licence, you as a user are not obliged to
  15 distribute wxWindows source code with your products. However,
  16 you are prevented from selling the code without permission from
  17 the authors, or denying others the rights to use or distribute
  18 wxWindows in the way intended.
  19
  20 The wxWindows Licence establishes the copyright for the code and
  21 related material, and it gives you legal permission to copy,
  22 distribute and/or modify the library. It also asserts that no
  23 warranty is given by the authors for this or derived code.
  24
  25 Finally, the licence specifies that any patent involving
  26 wxWindows, must be licenced for everyone's free use.

  31 Terms and conditions for copying, distribution and modification
  32
  33 1. This Licence Agreement applies to any software library which
  34 contains a notice placed by the copyright holder or other
  35 authorized party saying it may be distributed under the terms of
  36 this wxWindows Licence (also called "this Licence").  Each
  37 licencee is addressed as "you".
  38
  39 A "library" means a collection of software functions and/or data
  40 prepared so as to be conveniently linked with application
  41 programs (which use some of those functions and data) to form
  42 executables.
  43
  44 The "Library", below, refers to any such software library or
  45 work which has been distributed under these terms.  A "work
  46 based on the Library" means either the Library or any derivative
  47 work under copyright law: that is to say, a work containing the
  48 Library or a portion of it, either verbatim or with
  49 modifications and/or translated straightforwardly into another
  50 language.  (Hereinafter, translation is included without
  51 limitation in the term "modification".)
  52
  53 "Source code" for a work means the preferred form of the work
  54 for making modifications to it.  For a library, complete source
  55 code means all the source code for all modules it contains, plus
  56 any associated interface definition files, plus the scripts used
  57 to control compilation and installation of the library.
  58
  59 Activities other than copying, distribution and modification are
  60 not covered by this Licence; they are outside its scope. The act
  61 of running a program using the Library is not restricted, and
  62 output from such a program is covered only if its contents
  63 constitute a work based on the Library (independent of the use
  64 of the Library in a tool for writing it). Whether that is true
  65 depends on what the Library does and what the program that uses
  66 the Library does.
  67
  68 2. You may copy and distribute verbatim copies of the Library's
  69 complete source code as you receive it, in any medium, provided
  70 that you conspicuously and appropriately publish on each copy an
  71 appropriate copyright notice and disclaimer of warranty; keep
  72 intact all the notices that refer to this Licence and to the
  73 absence of any warranty; and distribute a copy of this Licence
  74 along with the Library.
  75
  76 You may charge a fee for the physical act of transferring a
  77 copy, and you may at your option offer warranty protection in
  78 exchange for a fee.
  79
  80 3. You may modify your copy or copies of the Library or any
  81 portion of it, thus forming a work based on the Library, and
  82 copy and distribute such modifications or work under the terms
  83 of Section 1 above, provided that you cause the files modified
  84 to carry prominent notices stating that you changed the files
  85 and the date of any change. With agreement from the authors of
  86 wxWindows, you may charge for value added to the Library, for
  87 example, a commercially supported version, or a port to a new
  88 platform. It is expected that collaboration between such
  89 commercial interests and the free wxWindows community will yield
  90 benefits to both parties, since wxWindows represents a
  91 substantial investment of time and effort. It is not in the
  92 spirit of this agreement that commercial exploitation of
  93 wxWindows should in any way detract from the free version.
  94
  95 4. You may copy and distribute the Library in object code or
  96 derived library form under the terms of Sections 1 and 2 above
  97 provided that you accompany it with the complete corresponding
  98 machine-readable source code.
  99
 100 If distribution of object code is made by offering access to
 101 copy from a designated place, then offering equivalent access to
 102 copy the source code from the same place satisfies the
 103 requirement to distribute the source code, even though third
 104 parties are not compelled to copy the source along with the
 105 object code.
 106
 107 5. You may not copy, modify, sublicence, link with, or
 108 distribute the Library except as expressly provided under this
 109 Licence.  Any attempt otherwise to copy, modify, sublicence,
 110 link with, or distribute the Library is void, and will
 111 automatically terminate your rights under this Licence.
 112 However, parties who have received copies, or rights, from you
 113 under this Licence will not have their licences terminated so
 114 long as such parties remain in full compliance.
 115
 116 6. You are not required to accept this Licence, since you have
 117 not signed it. However, nothing else grants you permission to
 118 modify or distribute the Library or its derivative works.  These
 119 actions are prohibited by law if you do not accept this Licence.
 120 Therefore, by modifying or distributing the Library (or any work
 121 based on the Library), you indicate your acceptance of this
 122 Licence to do so, and all its terms and conditions for copying,
 123 distributing or modifying the Library or works based on it.
 124
 125 7. Each time you redistribute the Library (or any work based on
 126 the Library), the recipient automatically receives a licence
 127 from the original licensor to copy, distribute, link with or
 128 modify the Library subject to these terms and conditions. You
 129 may not impose any further restrictions on the recipients'
 130 exercise of the rights granted herein. You are not responsible
 131 for enforcing compliance by third parties to this Licence.
 132
 133 8. If, as a consequence of a court judgment or allegation of
 134 patent infringement or for any other reason (not limited to
 135 patent issues), conditions are imposed on you (whether by court
 136 order, agreement or otherwise) that contradict the conditions of
 137 this Licence, they do not excuse you from the conditions of this
 138 Licence. If you cannot distribute so as to satisfy
 139 simultaneously your obligations under this Licence and any other
 140 pertinent obligations, then as a consequence you may not
 141 distribute the Library at all. For example, if a patent licence
 142 would not permit royalty-free redistribution of the Library by
 143 all those who receive copies directly or indirectly through you,
 144 then the only way you could satisfy both it and this Licence
 145 would be to refrain entirely from distribution of the Library.
 146
 147 If any portion of this section is held invalid or unenforceable
 148 under any particular circumstance, the balance of the section is
 149 intended to apply, and the section as a whole is intended to
 150 apply in other circumstances.
 151
 152 It is not the purpose of this section to induce you to infringe
 153 any patents or other property right claims or to contest
 154 validity of any such claims; this section has the sole purpose
 155 of protecting the integrity of the free software distribution
 156 system which is implemented by public licence practices. Many
 157 people have made generous contributions to the wide range of
 158 software distributed through that system in reliance on
 159 consistent application of that system; it is up to the
 160 author/donor to decide if he or she is willing to distribute
 161 software through any other system and a licencee cannot impose
 162 that choice.
 163
 164 This section is intended to make thoroughly clear what is
 165 believed to be a consequence of the rest of this Licence.
 166
 167 9. If the distribution and/or use of the Library is restricted
 168 in certain countries either by patents or by copyrighted
 169 interfaces, the original copyright holder who places the Library
 170 under this Licence may add an explicit geographical distribution
 171 limitation excluding those countries, so that distribution is
 172 permitted only in or among countries not thus excluded. In such
 173 case, this Licence incorporates the limitation as if written in
 174 the body of this Licence.
 175
 176 10. The authors of wxWindows may publish revised and/or new
 177 versions of the wxWindows Licence from time to time. Such new
 178 versions will be similar in spirit to the present version, but
 179 may differ in detail to address new problems or concerns.
 180
 181 Each version is given a distinguishing version number. If the
 182 Library specifies a version number of this Licence which applies
 183 to it and "any later version", you have the option of following
 184 the terms and conditions either of that version or of any later
 185 version published by the wxWindows authors.  If the Library does
 186 not specify a licence version number, you may choose any version
 187 ever published by the wxWindows authors.
 188
 189 11. If you wish to incorporate parts of the Library into other
 190 free programs whose distribution conditions are incompatible
 191 with these, write to the program author to ask for permission.
 192 For software which is copyrighted by the wxWindows authors,
 193 write to the wxWindows authors.  Our decision will be guided by
 194 the two goals of preserving the free status of all derivatives
 195 of our free software and of promoting the sharing and reuse of
 196 software generally.
 197
 198 NO WARRANTY
 199 -----------
 200
 201 12. BECAUSE THE LIBRARY IS LICENCED FREE OF CHARGE, THERE IS NO
 202 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE
 203 LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 204 HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT
 205 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
 206 BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY
 207 AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE
 208 QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU.  SHOULD THE
 209 LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
 210 SERVICING, REPAIR OR CORRECTION.
 211
 212 13. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO
 213 IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
 214 MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE
 215 LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
 216 INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
 217 INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS
 218 OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 219 YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH
 220 ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
 221 ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
