2 Mono is made up of many pieces of code, all of them open source, but
3 different pieces of Mono use different licensing terms.
5 For comments, corrections and updates, please contact mono@xamarin.com
9 Parts of Mono are dual licensed, they are available to the
10 public in GPL or LGPL forms, but we also offer those pieces
11 under commercial terms from Xamarin for the cases where the
12 GPL and the LGPL are not suitable.
14 We have tried to pick the licenses that will maximize adoption
15 of Mono, so we tend to use the MIT X11 or LGPL liceses.
17 Contributions to dual-licensed module require that the author
18 contributes the code under the terms of the MIT X11 code, or
19 to sign an agreement that allows Novell to redistribute the
20 code under other licenses.
22 Contributions for other modules should be under the same license
23 terms as the rest of the module, or under MIT X11 terms.

32 ** mono/mono: the Mono VM
34 This code is dual licensed under the LGPL or commercial licenses.
36 The LGPL ensures that Mono can be used in most scenarios, but
37 gives Xamarin the flexibility to relicense the code for
38 embedded systems, static linking or commercial settings where
39 the LGPL can not be used.
41 We consider non-LGPL use instances where you use this on an
42 embedded system where the end user is not able to upgrade the
43 Mono VM or Moonlight installation or distribution that is part
44 of your product (Section 6 and 7), you would have to obtain a
45 commercial license from Xamarin (consider software burned into
46 a ROM, systems where end users would not be able to upgrade,
47 an embedded console, a game console that imposes limitations
48 on the distribution and access to the code, a phone platform
49 that prevents end users from upgrading Moonlight).
51 Contact mono@xamarin.com for details on obtaining the Mono
52 runtime under other terms.
54 ** mono/support: MonoPosixHelper and support code
56 This code is dual licensed under the LGPL or commercial licenses, with
57 the same guidelines as mono/mono code.
59 The ZLib files are included under a "new BSD"-style license.
61 ** mono/eglib: Mono's X11 glib implementation
63 This is a minimal subset of glib that is to be licensed under
64 the terms of the MIT X11, this means that this code can be
65 used for any purposes by anyone.
67 ** mono/arch/*/XXX-codegen.h
69 This are C macros that are useful when generating native
70 code on various platforms. This code is MIT X11 licensed.
74 The C# Compilers (1.0 and 2.0)
76 These compilers are dual licensed under the GPL and MIT X11
81 Unless explicitly stated, the tests are under the MIT X11 license.
85 The class libraries developed by the Mono team are licensed
86 under the MIT X11 terms.
88 In addition to the class libraries developed by the Mono team,
89 there are a number of class libraries that we bundle as part
90 of the distribution that were integrated from third-parties or
91 that contain code that was originally licensed under different
98 FirebirdSql.Data.Firebird: Firebird public license.
99 See: mcs/class/FirebirdSql.Data.Firebird/license.txt
101 ICSharpCode.SharpZipLib, GPL with exceptions.
102 See: mcs/class/ICSharpCode.SharpZipLib/README
104 ** mcs/class/System.Core/System/TimeZoneInfo.Android.cs
106 This is a port of Apache 2.0-licensed Android code, and thus is
107 licensed under the Apache 2.0 license:
109 http://www.apache.org/licenses/LICENSE-2.0
114 These are licensed under the MIT X11 license, except where the
115 GPL is explicitly used.
119 This is a port of Berkeley yacc, so it is available under the BSD
120 license. See the license in the individual C files for details.
124 Manual pages and Mono documentation are covered by the MIT X11 license.
128 The code in the "samples" directory is released under the MIT X11 license.
