Where does that get handled? It isn't in the doc block before the field.
loadProfileFields is where the variable is filled with data.
Or you mean where the variable is actually used?
It's another of those meh things...
Yeah, I'm trying to find where the $options part is actually used.
Why are you asking questions only about meh code? :P
$options is used in several places all around the templates and controllers (maybe some subs too).
It should hold the per-user alternatives of the $settings.
Just wondering because it is a string of PHP code but it should probably be an anonymous function.
