Open-source licenses

• Strong copyleft: 3. If you distribute the program or anything built on it, you must release the whole source under the same license.
• Network copyleft: 1. Like GPL, and running a changed version as a web service counts as distributing it, so its users get the source too.
• Permissive: 1. Use it anywhere, including in closed products. You keep the copyright notice; Apache-2.0 also grants patent rights.
