Help Output

The help output is influenced by overriding methods on subclasses from both CLIFramework\Application and CLIFramework\Command.

Method to override	Description
public function brief(): string	A short piece of text (one line) that appears in the help output of the parent command, under the NAME header if defined in a command and at the very top if defined in the application.
public function usage(): string	Appears under the USAGE header.
public function help(): string	Appears at the bottom of the help output and can contain a long description.

Additionally, $this->setProgramName($name) can be called in the public init(): void method to influence the output of generated suggested commands. By default the program name is the first argument in $argv.
