Our license agreement contains conditions intended to keep
Squeak open and available to the user community, while letting users do useful things with Squeak. You will see the license once you begin installing Squeak. These following examples are provided as illustrations and are not legally binding. See the license for the real terms. To the extent that the examples and the license conflict, the license will govern.
You are allowed to change Squeak, write extensions to Squeak, build an application in Squeak, and include some or all of Squeak with your products. You may distribute all of these things along with Squeak, or portions of Squeak, for free or for money. However, you must distribute these things under a license that protects Apple in the way described in our license to you.
If you modify any of the methods of class objects (or their relationships) that come with Squeak (as opposed to building on top of what we provide), you must post the modifications on a web site or otherwise make them available for free to others, just as we have done with Squeak. Our license to you explains how you must do this.
The same is true if you port Squeak to another machine or operating system: you must post your port on a web site or otherwise make it available for free to others under the terms described in our license to you.
