#Thank you for Using RUBYBOOT Version 1.2
#This Script was developed for Duelboot Raspberry Pi's that are using
#Raspbian and RetroPie.  This is Not the final Script however.
#This Script will call the startx and emulationstation commands to load the OS,
#However, it autoloads IRB, the Interactive Ruby command Line to function.
#at this time, If you exit to the CLI, it will return you back into Irb after
#closing the Xwindow session of your OS.  To exit out of IRB, simply type 'exit'
#to return to the Linux CLI.
