Hey pfech, thanks for taking a look at WhiteBox.
The Machinery is unrelated to WhiteBox, other than that we have both presented at the Handmade Seattle conference.
You get access to Linux & Windows WhiteBox executables, plugins for a bunch of editors, and updates up to 1.X.
The license addresses the fact that this is not fully stable software, and that we’re not liable for its use. Commercial use is not restricted, although caution is recommended.
Let me know if you need any more details. Andrew
