cua-lite is a replacement of the CUA emulator package for Emacs. It was last updated in 2003. There are three things that make this package different from the others already out there:
In addition, it was designed to encourage people (individually as well as site admins) to make the package available for use without actually loading it.

See the source for details on the various ways to install & load the package. At its simplest, put this file on your LoadPath and add the following to your ~/.emacs startup file:
(require 'cua-lite) (cua-lite 1)
