 750 Usage: $0 [OPTION]... [VAR=VALUE]...
 751
 752 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 753 VAR=VALUE.  See below for descriptions of some of the useful variables.
 754
 755 Defaults for the options are specified in brackets.
 756
 757 Configuration:
 758   -h, --help              display this help and exit
 759       --help=short        display options specific to this package
 760       --help=recursive    display the short help of all the included packages
 761   -V, --version           display version information and exit
 762   -q, --quiet, --silent   do not print \`checking...' messages
 763       --cache-file=FILE   cache test results in FILE [disabled]
 764   -C, --config-cache      alias for \`--cache-file=config.cache'
 765   -n, --no-create         do not create output files
 766       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 771 Installation directories:

 774   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 775                           [PREFIX]
 776
 777 By default, \`make install' will install all the files in
 778 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 779 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 780 for instance \`--prefix=\$HOME'.
 781
 782 For better control, use the options below.

 784 Fine tuning of the installation directories:

 786   --sbindir=DIR          system admin executables [EPREFIX/sbin]

 807 Some influential environment variables:
 808   CC          C compiler command
 809   CFLAGS      C compiler flags
 810   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 811               nonstandard directory <lib dir>
 812   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have

 814   CXX         C++ compiler command
 815   CXXFLAGS    C++ compiler flags
 816
 817 Use these variables to override the choices made by `configure' or to help
 818 it to find libraries and programs with nonstandard names/locations.
