Fantastico is a commercial script library that automates the installation of web applications to a website.
Fantastico scripts are executed from the administration area of a website control panel such as cPanel.
Fantastico's web site claims that they are installed on ten thousand servers, with a million users worldwide.
The scripts typically create tables in a database, install software, adjust permissions, and modify web server configuration files.
Although Fantastico primarily targets open-source software, a handful of scripts are also available that install proprietary products.
