DESCRIPTION
 altqd is a daemon program that reads a configuration file and then sets up the ALTQ state of network interfaces. After configuring the ALTQ state, 
altqd will detach and become a daemon.
The signals SIGINT or SIGTERM will shutdown altqd, and the signal SIGHUP will restart altqd.
The following options are available:
- 
-d

Debug mode. altqd does not detach and goes into the command mode.
- 
-f conf_file
- 
Specify a configuration file to read instead of the default. The default file is /etc/altq.conf.
- 
-v
- 
Print debugging information. This option implies -d.
