supervisor
==========
Starts and restarts several "daemon" scripts with stdout and stderr redirected
into log files with timestamps added.
Name Heuristic
--------------
If supervisor is started as /usr/local/bin/start-something, configuration file
will will be loaded from /usr/local/etc/something/supervisor.conf.
To use this feature, use --enable-name-heuristic configure script option.

logdir = /home/vir
pidfile = ./supervisor.pid

autorestart = yes

log.timestamp = yes
log.microseconds = yes
[second]
cmd = ./tricky.pl second
autostart = yes
autorestart = no
