Where art thou 'rename'

[Rashkae]

In the days of yore, I often used a neat little program called rename to
 do bulk file renames.

I've just noticed in my Gutsy system that rename has since been replace
with a new perl program, which though more powerful, has dramatically
different syntax.

Here's a man page I found of the rename I know and love:

anyone know where I can find this program?
