description = [[
Obtains the CakePHP version of a web application built with the CakePHP
framework by fingerprinting default files shipped with the CakePHP framework.

This script queries the files 'vendors.php', 'cake.generic.css',
'cake.icon.png' and 'cake.icon.gif' to try to obtain the version of the CakePHP
installation.

Since installations that had been upgraded are prone to false positives due to
old files that aren't removed, the script displays 3 different versions:
* Codebase: Taken from the existence of vendors.php (1.1.x or 1.2.x if it does and 1.3.x otherwise)
* Stylesheet: Taken from cake.generic.css
* Icon: Taken from cake.icon.gif or cake.icon.png

For more information about CakePHP visit: http://www.cakephp.org/.
