Pagination library for Rails and other Ruby applications

WillPaginate::Collection#initialize

Arguments to the constructor are the current page number, per-page limit
and the total number of entries. The last argument is optional because it
is best to do lazy counting; in other words, count *conditionally* after
populating the collection using the +replace+ method.
