For tasks to be invoked they must be exposed as subcommands. If you define any subcommands, you must define all the subcommands your shell needs, whether they be methods on this class or methods on tasks.

Parameters

array $argv: Array of arguments to run the shell with. This array should be missing the shell name.
bool $autoMethod optional: Set to true to allow any public method to be called even if it was not defined as a subcommand. This is used by ShellDispatcher to make building simple shells easy.
