In Mac OS X services are launched by the launchd daemon. It searches for *.plist files in the /Library/LaunchDaemons folder. Then it reads its contents and launches corresponding daemons.
A sample of such a file is located in the service-tools.zip archive, in the macos-launchd folder.
The com.cerebrohq.cargador.plist file has a simple text format. You should configure the location of Cargador daemon, as well as user names and group names on behalf of which the service should be started. Pay attention to the following parameter:
<key>RunAtLoad</key>
<true/>
You can prevent Cargador daemon from launching on your server by changing its value to false.
