      DOSBox is an emulator that recreates a MS-DOS compatible environment
      (complete with Sound, Input, Graphics and even basic networking). This
      environment is complete enough to run many classic MS-DOS games completely
      unmodified. In order to utilize all of DOSBox's features you need to first
      understand some basic concepts about the MS-DOS environment.
