Adds a Theme option to any active theme allowing you to make a child theme.

One-Click Child Theme

Please visit the <a href="http://terrychay.com/wordpress-plugins/one-click-child-theme" rel="nofollow">plugin homepage</a>.
Useful for shared hosts, this allows you to easily create child themes from any 
theme just by clicking.
Ever since WordPress 3.0, you shouldn’t directly modify CSS of any downloaded 
themes because if you update the theme, your changes will be destroyed. Instead, it is recommended that you create a child theme and edit the CSS 
there so that updates to the parent theme will be inherited instead of destroy 
your changes.
The problem many run into is currently the only way to child theme something 
is edit files on the filesystem. This is non-intuitive for shared-hosting 
sites with one-click WordPress installs (it usually involves a “shell account” 
or learning how to use FTP).
This attempts to get around that issue, by adding a button to the themes page 
to allow you to child theme the page. (It’s not really one-click, though.)
