Clang. Introduction

Hello dear Clang community! I wanted to ask you:

  1. Is Clang a compiler?
  2. Is clang completely free? Can I use Clang for commercial and non-commercial projects for free? And not pay any fees?
  3. If I use it for commercial and non-commercial projects, do I have to contribute to clang? Or is it optional?
  1. Yes
  2. Yes. Yes. Correct.
  3. No, it’s optional.
