Use at your own risk... 

\"Installation\" Copy the send_gmail.py into Nagios\' libexec directory, and make the following changes to the commands.cfg file. Note, your installation may vary.  See python script for a bit more documentation.

I\'m interested in any comments or improvements that you have for this script.
