+Pagination
+==========
+
+To install:
+
+  script/plugin install svn://errtheblog.com/svn/plugins/classic_pagination
+
+This code was extracted from Rails trunk after the release 1.2.3.
+WARNING: this code is dead. It is unmaintained, untested and full of cruft.
+
+There is a much better pagination plugin called will_paginate.
+Install it like this and glance through the README:
+
+  script/plugin install svn://errtheblog.com/svn/plugins/will_paginate
+
+It doesn't have the same API, but is in fact much nicer. You can
+have both plugins installed until you change your controller/view code that
+handles pagination. Then, simply uninstall classic_pagination.

+  # The Pagination module aids in the process of paging large collections of
+  # Active Record objects. It offers macro-style automatic fetching of your
+  # model for multiple views, or explicit fetching for single actions. And if
+  # the magic isn't flexible enough for your needs, you can create your own
+  # paginators with a minimal amount of code.
+  #
+  # The Pagination module can handle as much or as little as you wish. In the
+  # controller, have it automatically query your model for pagination; or,
+  # if you prefer, create Paginator objects yourself.
