	RecipientManager provides an interface that allows the user to manage 
	the list of individuals who are notified when notifications are sent
	out. Recipient manager lets the user add or remove recipients from the
	list as well as list all current recipients.

	The list/database managed by RecipientManager SHOULD be remote because
	the purpose of this tool is to verify system integrity. Relying on a 
	local list means that the integrity of the tool could be compromised
	in the same manner as the files whose interity it is trying to verify.

	The list/database CAN be kept on the same server as the checksum database
	because the integrity of that server is assumed to be intact for the
	purposes of verification.
