/**
 * Pho ... undation!
 *
 * This is the standard phoundation command execution script.
 *
 * With this script you can execute all Phoundation scripts. It supports auto complete so please try and use <TAB> to
 * find sub commands, but also use <TAB> in sub commands as most support auto complete with nearly all parameters.
 *
 * This script will also ensure that all required PHP modules and all vendor directories are installed using PHP
 * composer (included in your Phoundation installation in ROOT/data/bin)
