# The pidfile for the reporter daemon.

# nc is netcat, it sends tcp to given host port. It makes a tcp connection
|
|
# and writes one log-line to it (grepped from the logfile).

# the notify command can be: "nc the.server.name.org 1234"
|
|
# the listening daemon could be: nc -lk 127.0.0.1 1234 >> outputfile &
