# description: Starts and stops sc_serv. 
#	       You know, the mp3 streaming thang.
#
#	Version 1.3 (nov 4 2001)
#	Now with more revisions! System now checks for pid file before cat
#	to display so that we receive no error messages. System also displays
#	pids as we are killing old processes. Profanity was removed from the 
#	startup messages. Tests for a pid file before reporting success. Displays
#	the relay server name when we start the daemon up, so that we know
#	which servers are getting booted. Pushed the success marker over to the 
#	right and added [] because I am just a slave to fashion.
#
#	Version 1.2 (nov 3 2001)
#	Same exact shit, but runs as nobody for security reasons. Just
#	in case we are worried about buffer overflows or whatnot.
#	
#	Version 1.1 (nov 3 2001)
#	Starts stops and restarts jobs. Also checks for existing daemons
#	before calling a start, and exits without starting new ones. This
#	prevents you from being a dumbass and starting multiple listeners
#	on the same port. I would suggest using the restart command
#	in these cases. Also creates a shoutcast.pid file that can be used
#	to discover all of the (many) pids used by shoutcast when running.
#
#	Version 1.0 (nov 3 2001) 
#	Starts and stops successfully. 
#	Kills old jobs on start command. Dirty, but 
#	does the job well enough. Tested functional on
#	mandrake version 8.1 but should work on redhat 
#	or any other distro that supports a standard 
#	sysv startup script.
#
#	Instructions for use.
#	1: untargzip shoutcast into the directory of your choosing
#	2: copy sc_serv into the /usr/sbin directory 
#	3: Create the directory /etc/shoutcast
#	4: copy the shoutcast.conf file into your /etc/shoutcast dir.
#	5: Edit the shoutcast.conf file to match your needs.
#	6: Make as many more conf files as needed to support 
#	   multiple streams. Be sure to edit these files so that
#	   you are not starting multiple shoutcast servers that
#	   are either listening or broadcasting on the same port.
#	7: Copy this file into the /etc/rc.d/init.d directory
#	8: chmod this file +x (chmod ug+x /etc/rc.d/init.d/shoutcast)
#	9: run chkconfig --add shoutcast from the /etc/rc.d/init.d dir.
#	10:Run /etc/rc.d/init.d/shoutcast start 
#	11:Drink a beer, or light one up, and enjoy the tunes.
