[stunnel-users] Starting stunnel automatically on OS X system startup

[Allen]

Does anybody have a solution that will start up stunnel on OS X  
bootup? I've installed stunnel on a Leopard server (OS 10.4.5.4) to  
make a smtp SSL relay work (and it works fine). The problem is, we'd  
have to type in /opt/local/bin/stunnel on the command line every time  
the server is rebooted. Rather than having to create a /Library/ 
SystemStartup/diretory_structure_with_plist_etc., has somebody done  
this, and can lead me in the right direction, in the interest of time?  
I've just run out of time, and I kinda think that somebody must have  
done this already.

Thanks!

Allen
