bbfix functionality in hobbit

Is there any method with hobbit to have the client automatically
restart services, like bbfix does for BB?  We would like to be able to
restart services that tend to fail often (such as SSH tunnels)
automatically through Hobbit.  Without writing a custom external
script, I can't seem to find any information about doing this.

Thanks all for your responses.  It has provided me with a lot more
information that I could have hoped ;-)
