The launchctl(1) and launchd.plist(5) man pages were substantially updated in 
Yosemite to cover new functionality, address a bunch of clarity errors, and 
remove stuff that was no longer relevant. launchctl(1) itself also has fairly 
extensive help for each subcommand.

If documentation in either the man pages or launchctl(1)'s help output is 
unclear/incorrect, please file a bug.
