792	--help=recursive display the short help of all the included packages
793	-V, --version display version information and exit
794	-q, --quiet, --silent do not print \`checking...' messages
795	--cache-file=FILE cache test results in FILE [disabled]
796	-C, --config-cache alias for \`--cache-file=config.cache'
