+ --status output a synopsis with all parameters affecting the

+ --query like --status, but in deb822 format.
+ --query-features <area>
+ output the status of features for the given area.
+ --list output a list of the flags supported by the current vendor.
+ --export=(sh|make|cmdline|configure)
+ output something convenient to import the compilation
+ flags in a shell script, in make, or in a command line.
+ --dump output all compilation flags with their values.
+ --help show this help message.
