s3cmd is working fine in But launchd can't run s3cmd. I see in system.log errors like:

Mar  5 12:48:17 kinds-MacBook com.kind.s3cmd[13060]: ERROR: Can't find a config file. Please use --config option.
Mar  5 12:48:17 kinds-MacBook[1] (com.kind.s3cmd[13060]): Exited with exit code: 1

How can I use s3cmd with launchd?
