title: How to convert a compiled protocol buffer back to .proto file?
body: <p>I have a compiled google protocol buffer for python 2 and I'm attempting to port this to python 3. Unfortunately, I cannot find the proto file I used to generate the compiled protocol buffer anywhere. How do I recover the proto file so that I can compile a new one for python 3. I'm unaware of what proto versions were used and all I have is the .py file meant to run on python 2.6.</p>
