Usage
This is part of Template:AzB player. It is not used by itself. Basically, it is a pseudo-loop. It does some simple math checks to make sure a year supplied to it is within a specific range (2000 and up), exits if not, but if so, displays a bullet and year link, then decrements year by 1 and calls itself again via a redirect as long as the decremented year is also within the specific range. }}
