RT Templates

I'd like to create a standard header or footer on RT tickets.

========= PS:One Ping =========
{$Transaction->CreatedAsString}: PS:One Ping {$Ticket->id} was acted upon.
Transaction: {$Transaction->Description}
Queue: {$Ticket->QueueObj->Name}
Subject: {$Transaction->Subject || $Ticket->Subject || "(No subject given)"}
Owner: {$Ticket->OwnerObj->Name}
Requestors: {$Ticket->RequestorAddresses}
Status: {$Ticket->Status}
Ticket <URL: {RT->Config->Get('WebURL')}Ticket/Display.html?id={$Ticket->id} >
