-# Any UI module that is installing events is changed so that the
-# events are installed using the ``set_gdb_events()'' and
-# ``gdb_event_hooks()'' interfaces.  There could prove to be an issue
-# here with respect to annotate.  We might need to accomodate a hook
-# stack that allows several ui blocks to install their own events.
-
-# Each of the variable events (as currently generated) is converted
-# to either a straight function call or a function call with a
-# predicate.
