PM Tasks

Does anyone have a definitive/comprehensive list of what a Project Manager does?
What I mean is, as well as the overall tasks such as ‘Managing the Project’ and ‘Responsible for its Success’, what does it involve on a day-to-day basis to achive these goals?
Rather than what skills and experience the PM should have, what I am looking for is a list of tasks, responsibilities, duties, authority, etc. that the PM has perform.
Any help would be much appreciated.
