The will_paginate library provides a simple, yet powerful and extensible API for pagination and rendering of pagination links in ActionView templates.

Pagination is just limiting the number of records displayed, showing a subset of them at any given view, and allowing you to move the displayed window. This plugin makes the whole process a breeze.

Although this package is aimed at being used from the Ruby on Rails framework, any Enumerable class can include WillPaginate, giving it this functionality.
