Subject: Ruby script for being notified of important e-mail

Hi all!

	I wanted to be notified in a dramatic way when an e-mail comes in
from a particular domain.  I use Mozilla for my e-mail on WinXP.  The
following Ruby script checks my Mozilla Inbox every 30 seconds and alerts
me by playing a MP3 file whenever a new message from that specific domain
comes in.  I thought someone else might find this useful, so here it is...
Enjoy.  Public Domain.  No guarantees.  No warranties.  Etc.

PS: I start it from a shell using "rubyw check_email.rb".  If you use "rubyw"
     then it starts in the background and has no console... so you won't even
     know if it is running unless you check the Task Manager for a "rubyw"
     process.  I like running it that way because I can start it and forget
     about it, and I don't need a dedicated console window opened to it.
