I want to convert library, which is licensed under Apache 2.0, to another programming language. The port will be initially pretty straightforward, i.e. I'll keep classes hierarchy and identifier names.
By no means I want to compromise copyright of original authors or change the license. Should I just copy LICENSE file and state in readme that this is a port? Or should I keep copyright comments in the code? In latter case, should I keep only original authors in copyright or add myself too?
