                                     LogPublisher

Publish log events to anyone subscribed to our 'logport'.

This class manages the subscriptions.

Enable this by asking the Tub for a reference to me, or by telling the Tub to offer me to a log gatherer:

lp = tub.getLogPort()
rref.callRemote('have_a_logport', lp)
print 'logport at:', tub.getLogPortFURL()

tub.setOption('log-gatherer-furl', gatherer_furl)

Running 'flogtool tail LOGPORT_FURL' will connect to the logport and print all events that subsequently get logged.

To make the logport use the same furl from one run to the next, give the Tub a filename where it can store the furl. Make sure you do this before touching the logport:

logport_furlfile = 'logport.furl'
tub.setOption('logport-furlfile', logport_furlfile)

If you're using a LogGatherer, pass its FURL into the Tub with tub.setOption('log-gatherer-furl'), or pass the name of a file where it is stored with tub.setOption('log-gatherer-furlfile'). This will cause the Tub to connect to the gatherer and grant it access to the logport.
