Web paging class utility

[Useko Netsumi]

I came across this utilities that has the following features:

a.. Create dynamic pages in minutes with this easy to use PHP class
a.. Manipulate results before they have been displayed
a.. All result formatting is completely customisable
a.. Automatically builds result navigation links
a.. Works with mySQL or Oracle (via ezSQL)
a.. Saves hours of programming

(please follow this link http://www.justinvincent.com/ )

It is quite easy to implement it using any database(MySQL, ORACLE,
POSTGRES).

I was wondering if we have it in pure Ruby solution? Perhaps it can be done
with less code. Thanks
