#
# Description: sends email to a sysadmin whenever a takeover occurs.
#
#	Note: This command requires an argument, unlike normal init scripts.
#
#	This can be given in the haresources file as:
#
#	You can also give a mail subject line or even multiple addresses
#		MailTo::[e-mail]::BigImportantWebServer
#		MailTo::[e-mail],[e-mail]::BigImportantWebServer
#
#	This will then be put into the message subject and body.
#
#	  OCF parameters are as below:
#		OCF_RESKEY_email
#		OCF_RESKEY_subject
