 1289:   -h, --help              display this help and exit
 1290:       --help=short        display options specific to this package
 1291:       --help=recursive    display the short help of all the included packages
 1292:   -V, --version           display version information and exit
 1293:   -q, --quiet, --silent   do not print \`checking ...' messages
 1294:       --cache-file=FILE   cache test results in FILE [disabled]
