# Resource script for sending WinPopups using smbclient
# derived from Alan Robertson's MailTo script
#
# Author: Sandro Poppi <spoppi@gmx.de>
#
# Description: sends WinPopups to a sysadmin's workstation
#	       whenever a takeover occurs.
#
#	Note: This command requires an argument, unlike normal init scripts.
#
#	This can be given in the haresources file as:
#
#		WinPopup::hosts
#
#	where "hosts" is a file containing the IPs/Workstation names
#	one by line to be sent WinPopups
