我想在 GPLv3 下发布一个小软件。它是用 C# 为 .NET 3.5 SP1 框架编写的。它还使用在 MS-PL 下发布的MEF库。MS-PL 不兼容 GPL。但是，MEF 库最终会被滚动到 .NET 4 版本中，到那时，它就变成了一个系统库，不再重要了。
我仍然希望尽快发布代码，只是为了获得一些反馈并为早期采用者提供代码（尽早发布，经常发布）。我知道我可以在 GPLv3 第 7 节下编写一个例外，允许接收者将此代码与此特定库链接。
这个异常会是什么样子？它是否位于项目目录中 LICENSE 文件旁边的单独文件中？我是否也必须在所有文件头中提及异常？我知道 ClassPath 异常，但有谁知道某个特定库发生异常的情况，例如？
我在开源项目 Vidalia 中找到了一个示例。您可以查看他们的LICENSE 文件以了解他们如何允许链接到 OpenSSL：
