It's just any function you like to get called when the user presses
the button which causes the DELETE_WINDOW request (it's the `puts' in
your example).  Usually it is some cleanup routine (eg, the same as
you would have under File->Exit), but it might also
be just (again, in Tk notation)
  wm protocol {.} WM_DELETE_WINDOW { # do nothing }
  wm protocol {.} WM_DELETE_WINDOW { wm withdraw {.} }
In these examples I assume you know what you're doing there, and that
your users have some other means of terminating the application ;-)
