    The main function of the task is to work through the "AfC submissions by
    date" categories (e.g. [[Category:AfC submissions by date/12 July 2011]])
    and determine the number of declined, accepted, and currently pending
    submissions every day.

    used to generate a graph showing the number of AfC submissions by date
