+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:
+
+ COPYING-LGPL-2.1
+ COPYING-MPL-1.1
+
+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.
