FAQ
What license does Wrench.js use?
Wrench.js is currently uses the MIT License.
Note that license is still lightly up for debate. Wrench.js does not plan to move away from MIT to anything more restrictive, however multi-licensing the project is a possibility if it would make it easier to share code with other projects.
For that reason we ask that anyone commiting to the project either transfer copyright to the project head, or give the project permission ahead of time to relicense their contributions along with the rest of the project as long as it fits in with that goal.
