Debugging a task, that's sending emails to too many customers.
Supervisor: "Never mind, just test in production, there is a dry run flag for the tasks."
Just in case I test locally...
Flags tried:
--dryrun="TRUE" => Error, failed to send mail.
--dryrun=TRUE => Error, failed to send mail.
--dryrun="true" => Not trying to send mail.

If it's THIS PICKY a little more documentation would be nice.
And by a little more I mean: more than the task base class in a giant php monstrosity without phpdocs expecting its code to be self-documenting.
