Mono is made up of many pieces of code, all of them open source, but
|
|
different pieces of Mono use different licensing terms.
|
|
|

For comments, corrections and updates, please contact mono@xamarin.com
|
|
|
|
* Dual Licensing
|
|
|
|
Parts of Mono are dual licensed, they are available to the
|
|
public in GPL or LGPL forms, but we also offer those pieces
|
|
under commercial terms from Xamarin for the cases wher the GPL
|
|
and the LGPL are not suitable.
|
|
|
|
We have tried to pick the licenses that will maximize adoption
|
|
of Mono, so we tend to use the MIT X11 or LGPL liceses.
|
|
|
|
Contributions to dual-licensed module require that the author
|
|
contributes the code under the terms of the MIT X11 code, or
|
|
to sign an agreement that allows Novell to redistribute the
|
|
code under other licenses.
|
|
|
|
Contributions for other modules should be under the same license
|
|
terms as the rest of the module, or under MIT X11 terms.
|
|
|
|
For the actual license links in the Mono distribution see the
|
|
bottom of this file.

|
* The Modules
|
|
|
|
** mono/mono: the Mono VM
|
|
|
|
This code is dual licensed under the LGPL or commercial licenses.
|
|
|
|
The LGPL ensures that Mono can be used in most scenarios, but
|
|
gives Xamarin the flexibility to relicense the code for
|
|
embedded systems, static linking or commercial settings where
|
|
the LGPL can not be used.
|
|
|
|
We consider non-LGPL use instances where you use this on an
|
|
embedded system where the end user is not able to upgrade the
|
|
Mono VM or Moonlight installation or distribution that is part
|
|
of your product (Section 6 and 7), you would have to obtain a
|
|
commercial license from Xamarin (consider software burned into
|
|
a ROM, systems where end users would not be able to upgrade,
|
|
an embedded console, a game console that imposes limitations
|
|
on the distribution and access to the code, a phone platform
|
|
that prevents end users from upgrading Moonlight).
|
|
|
|
Contact mono@xamarin.com for details on obtaining the Mono
|
|
runtime under other terms.
|
|
|
|
** mono/support: MonoPosixHelper and support code
|
|
|
|
This code is dual licensed under the LGPL or commercial licenses, with
|
|
the same guidelines as mono/mono code.
|
|
|
|
The ZLib files are included under a "new BSD"-style license.
|
|
|
|
** mono/eglib: Mono's X11 glib implementation
|
|
|
|
This is a minimal subset of glib that is to be licensed under
|
|
the terms of the MIT X11, this means that this code can be
|
|
used for any purposes by anyone.
|
|
|
|
** mono/metadata/sgen*: Mono's Copying Collector
|
|
|
|
This new garbage collector is licensed under the terms of
|
|
the MIT X11 license, in hopes that the GC could be reused
|
|
by third party projects, follows the same spirit than the
|
|
Boehm GC.
|
|
|
|
** mono/arch/*/XXX-codegen.h
|
|
|
|
This are C macros that are useful when generating native
|
|
code on various platforms. This code is MIT X11 licensed.
|
|
|
|
** mcs/mcs, mcs/gmcs
|
|
|
|
The C# Compilers (1.0 and 2.0)
|
|
|
|
These compilers are dual licensed under the GPL and MIT X11
|
|
license terms.

|
** mcs/class
|
|
|
|
The class libraries developed by the Mono team are licensed
|
|
under the MIT X11 terms.
|
|
|
|
In addition to the class libraries developed by the Mono team,
|
|
there are a number of class libraries that we bundle as part
|
|
of the distribution that were integrated from third-parties or
|
|
that contain code that was originally licensed under different
|
|
terms, these are:
|
|
|
|
ByteFX.Data: LGPL
|
|
|
|
Npgsql: LGPL
|
|
|

See: mcs/class/ICSharpCode.SharpZipLib/README
|
|
|
|
** mcs/class/System.Core/System/TimeZoneInfo.Android.cs
|
|
|
|
This is a port of Apache 2.0-licensed Android code, and thus is
