[Boost-users] [program_options] Notifiers

How does one install a notifier for an option that does not have a
value?  For example, if I have an option --foo and I want to call
foo_handler() when it is parsed, how do I do that?  As far as I
can tell from the documentation the only way to install a notifier
is through a value_semantic, which doesn't apply here.
