Open-source licenses

• Permissive: 20. Use it anywhere, including in closed products. You keep the copyright notice; Apache-2.0 also grants patent rights.
• Network copyleft: 5. Like GPL, and running a changed version as a web service counts as distributing it, so its users get the source too.
• Strong copyleft: 3. If you distribute the program or anything built on it, you must release the whole source under the same license.
• Weak copyleft: 2. Changes to the licensed files must be shared, but you can link them into a closed program.
