Recently, while preparing for an introductory Exam on UNIX, I learnt that the manual is divided into 8 sections. While going through the manual, I found a 'games' section (6). I saw a program called 'espdiff' and wanted to try it...
Here is a sample run:
$ espdiff
Please concentrate...
No brainwave activity detected. Aborting.

I don't understand what this means and suprisingly, the manual didn't help also. Could you explain what this game is about and how to use it?
man espdiff
