|Cairo is free software.
|Every source file in the implementation[*] of cairo is available to be
|redistributed and/or modified under the terms of either the GNU Lesser
|General Public License (LGPL) version 2.1 or the Mozilla Public
|License (MPL) version 1.1. Some files are available under more
|liberal terms, but we believe that in all cases, each file may be used
|under either the LGPL or the MPL.
|See the following files in this directory for the precise terms and
|conditions of either license:
|Please see each file in the implementation for copyright and licensing
|information, (in the opening comment of each file).
|[*] The implementation of cairo is contained entirely within the "src"
|directory of the cairo source distribution. There are other components
|of the cairo source distribution (such as the "test", "util", and "perf")
|that are auxiliary to the library itself. None of the source code in these
|directories contributes to a build of the cairo library itself, (libcairo.so
|or cairo.dll or similar).
|These auxiliary components are also free software, but may be under
|different license terms than cairo itself. For example, most of the
|test cases in the perf and test directories are made available under
|an MIT license to simplify any use of this code for reference purposes
|in using cairo itself. Other files might be available under the GNU
|General Public License (GPL), for example. Again, please see the COPYING
|file under each directory and the opening comment of each file for copyright
|and licensing information.
