popexec is a program for Unix/Linux which checks a POP e-mail account and then runs a program whenever new e-mail arrives. It can also optionally run a program when it sees that you no longer have new e-mail in your POP box. Examples are included which show you how to: Write "You have mail" or "You have X new messages" to a terminal, make a terminal beep, play an audio file, pop an X window onto the screen, make your keyboard LEDs blink, change your desktop background.
