+      "Commodore BASIC" (cbmbasic) is a 100% compatible version of Commodore's
+      version of Microsoft BASIC 6502 as found on the Commodore 64. You can use
+      it in interactive mode or pass a BASIC file as a command line parameter.
+
+      This source does not emulate 6502 code; all code is completely native. On
+      a 1 GHz CPU you get about 1000x speed compared to a 1 MHz 6502.
