title: Writing Clang tools without compiling clang
body: <p>I am not sure I understand this correctly, but this is my understanding:</p>
  
  <p>In order to compile a tool using clang's code (such as a source to source translator), you have to get the clang source, make it and then link your code to clang's source.</p>
  
  <p>Is my understanding correct, or is there a library that I could just download and link my code to that instead?</p>
