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

 910 Some influential environment variables:
 911   CC          C compiler command
 912   CFLAGS      C compiler flags
 913   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 914               nonstandard directory <lib dir>
 915   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
 916               headers in a nonstandard directory <include dir>
 917   CPP         C preprocessor
 918   CXX         C++ compiler command
 919   CXXFLAGS    C++ compiler flags
 920
 921 Use these variables to override the choices made by `configure' or to help
 922 it to find libraries and programs with nonstandard names/locations.
