With the advent of Yii 1.1.10 the package manager of the CClientScript became even more powerful with the ability to dynamically add packages to the list and chain the return value.

Most people who have used Yii for a while are quite familiar with using the clientScript component to dynamically add CSS and Javascript files to the page headers, so lets start there.
