//  Scripting.cpp
//
//  Executes custom scripts for various events in EmulationStation.
//  By calling fireEvent() the scripts inside the directory corresponding to the
//  argument 'eventName' will be executed with arg1 and arg2 as the script arguments.
//
//  The scripts are searched for in $HOME/.emulationstation/scripts/<eventName>.
//  For example, if the event is called 'game-start', all scripts inside the directory
//  $HOME/.emulationstation/scripts/game-start/ will be executed.
