The "/debug_tktnew" page:

Enter a new ticket.  The tktnew_template script in the ticket
configuration is used.  The /tktnew page is the official ticket
entry page.  The /debug_tktnew page is used for debugging the
tktnew_template in the ticket configuration.  /debug_tktnew works
just like /tktnew except that it does not really save the new ticket
when you press submit - it just prints the ticket artifact at the
top of the screen.
