    This script will utilize an API to minimize CSS and 
    JS source files.

    The intended use is with "minimize-prep", a PHP utility 
    that reads <link> and <script> tags and collects the 
    resource files it finds. It will create files that are 
    the concatenation of the CSS and JS files.

    Then this script is used for minimizing the files that were 
    created by "minimize-prep".
