 786 Usage: $0 [OPTION]... [VAR=VALUE]...
 787
 788 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 789 VAR=VALUE.  See below for descriptions of some of the useful variables.
 790
 791 Defaults for the options are specified in brackets.
 792
 793 Configuration:
 794   -h, --help              display this help and exit
 795       --help=short        display options specific to this package
 796       --help=recursive    display the short help of all the included packages
 797   -V, --version           display version information and exit
 798   -q, --quiet, --silent   do not print \`checking...' messages
 799       --cache-file=FILE   cache test results in FILE [disabled]
 800   -C, --config-cache      alias for \`--cache-file=config.cache'
 801   -n, --no-create         do not create output files
 802       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
