Get List of Signatures of Messages to Monobehaviour

I would like to programmatically generate a list of all the messages that Monobehaviour can receive, something along the lines of:

 void Awake();
 ...
 void OnCollisionEnter(Collision other);
 ...
 void Update();

Getting this as a list of MethodInfo instances would probably be most convenient, but text would be ok too.

I can't use reflection on Monobehaviour, because these messages are not members of Monobehaviour.

Thanks for any suggestions!

UPDATE: I ended up using a tool in JetBrains' resharper-unity plugin (apache license) called ApiParser that generates an xml file with the information I wanted (names, return types, parameter types of the messages). It uses the documentation, just as Bunny83 suggested in the answer below. From this, it was pretty easy to generate the source files that I wanted. Hopefully this will be easier and more robust than hand-coding the classes every time the api changes.
