class Byebug::SaveCommand

def description
  %{save[ FILE]
    Saves current byebug state to FILE as a script file. This includes
    breakpoints, catchpoints, display expressions and some settings. If
    no filename is given, we will fabricate one.
    Use the "source" command in another debug session to restore them.}
