Options:
	--help
		Display this help message.

	--silent
		Don't produce any output.

	--schemedir=DIR
		Use DIR as scheme directory.

	--no-strict-sections
		Don't treat sections found in config but not in scheme as error.

	--no-strict-options
		Don't treat options found in config but not in scheme as error.

	--no-strict-validators
		Don't invalidate config if an external validator fails.

	--no-strict-lists
		Don't invalidate lists that are stored options.

Actions:
	verify
		Validate given configuration, section or option.

	genspec
