title: Restoring .proto file from descriptor string. Possible?
body: <p>Is it possible to decompile a string containing Protocol Buffers descriptor back to .proto file? </p>
  
  <p>Say I have a long string like</p>
  
  <p><code>\n\file.proto\u001a\u000ccommon.proto\"\u00a3\u0001\n\nMsg1Request\u0012\u0017\n\u0006common\u0018\u0001 ...</code> etc.</p>
  
  <p>I need to restore .proto, not necessary exactly as it was but compilable.</p>
