"""Monitor a Tahoe grid, by playing sounds in response to remote events.

To install:
 1: install Boodler, from http://www.eblong.com/zarf/boodler/
 2: run "boodler.py -l listen.Sounds". This will run a daemon
    that listens on a network socket (31863 by default) and
    accepts commands in the form of "sound bird/crow1.aiff\n"
 3: copy this file into a new directory, which we'll call $BASEDIR
 4: write one or more logport FURLs into files named *.furl or *.furls, one
    per line. All logports from all such files will be used.
 5: launch this daemon with 'cd $BASEDIR && twistd -y boodlegrid.tac'
