launchd

On my Linux box I got cron task that runs script that uses sitecopy to upload new images to stock agencies every night. Cron is available on Mac but OS X is was deprecated and recommended method is launchd daemon.
My cron task runs shell script on weekdays:

# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (- installed on Tue Feb 3 19:39:38 2009)
# (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $)
0 3 * * 0,1,2,3,4,5 /home/mordor/bin/autostock.sh


I am newbie on Mac so I searched for GUI interface to launchd. I found information about lingon on Apple Downloads. 

It helped me to create my first plist:
