+      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

+      understand some basic concepts about the MS-DOS environment.
