I have some code I've posted on git hub (https://github.com/blackears/Photoshop-Perspective-Tool) and recently I got an email from someone wanting to know how they might use it in their own project, and in particular they need to attribute license information.
From what they've stated, it sounds like they've broken my original single file into several separate files. They also mentioned that they'd like to release it under a new license, but they didn't say which one. They also say they've added some new content in the form of additional UI boxes.
I'm not an expert with licenses. How does the Apache V2 deal with modifying and releasing code in a new form? What's the correct way for this new project to attribute my original repository?
