Many add-ons allow their source code to be openly viewed. This does not mean that the source code is open source or available for use in another add-on. The original author of an add-on retains copyright of their work unless otherwise noted in the add-on's license.
许多附加组件允许公开查看其源代码，但这并不代表源代码是以开源许可协议授权或者可在其他附加组件中使用。除非在附加组件的许可协议中另有注明，否则附加组件的原作者保留他们作品的著作权。
