- * To go into man page:

- * Synosis: emu-lejosrun [-v] bin_file

- * Description: Executes a binary file created by the lejos compiler within
- * Unix rather than in the RCX environment. The Java byte-codes
- * are executed here, and their actions are listed rather than
- * executed as they would be on the real RCX device.
- *
- * Options: -v Verbose mode. Normally the output is printed in raw
- * mode. The actual hex values are printed. Using this
- * option displays more user-friendly output.
