1Preamble 2======== 3 4The licensing of the wxWidgets library is intended to protect the wxWidgets 5library, its developers, and its users, so that the considerable investment 6it represents is not abused. 7 8Under the terms of the wxWidgets Licence, you as a user are not 9obliged to distribute wxWidgets source code with your products, if you 10distribute these products in binary form. However, you are prevented from 11restricting use of the library in source code form, or denying others the 12rights to use or distribute wxWidgets library source code in the way 13intended. 14 15The wxWidgets Licence establishes the copyright for the code and related 16material, and it gives you legal permission to copy, distribute and/or 17modify the library. It also asserts that no warranty is given by the authors 18for this or derived code. 19 20The core distribution of the wxWidgets library contains files 21under two different licences: 22 23- Most files are distributed under the GNU Library General Public 24 Licence, version 2, with the special exception that you may create and 25 distribute object code versions built from the source code or modified 26 versions of it (even if these modified versions include code under a 27 different licence), and distribute such binaries under your own 28 terms. 29 30- Most core wxWidgets manuals are made available under the "wxWidgets 31 Free Documentation Licence", which allows you to distribute modified 32 versions of the manuals, such as versions documenting any modifications 33 made by you in your version of the library. However, you may not restrict 34 any third party from reincorporating your changes into the original 35 manuals. 36 37Other relevant files: 38 39- licence.txt: a statement that the wxWidgets library is 40 covered by the GNU Library General Public Licence, with an 41 exception notice for binary distribution. 42 43- licendoc.txt: the wxWidgets Documentation Licence. 44 45- lgpl.txt: the text of the GNU Library General Public Licence. 46 47- gpl.txt: the text of the GNU General Public Licence, which is 48 referenced by the LGPL. 49 50
