  'configure' configures GNU coreutils 8.14a to adapt to many kinds of systems.
  
  Usage: ./configure [OPTION]... [VAR=VALUE]...
  
  To assign environment variables (e.g., CC, CFLAGS...), specify them as
  VAR=VALUE.  See below for descriptions of some of the useful variables.
  
  Defaults for the options are specified in brackets.
  
  Configuration:
    -h, --help              display this help and exit
        --help=short        display options specific to this package
        --help=recursive    display the short help of all the included packages
    -V, --version           display version information and exit
    -q, --quiet, --silent   do not print 'checking ...' messages
        --cache-file=FILE   cache test results in FILE [disabled]
    -C, --config-cache      alias for '--cache-file=config.cache'
    -n, --no-create         do not create output files
        --srcdir=DIR        find the sources in DIR [configure dir or '..']
  
  Installation directories:
    --prefix=PREFIX         install architecture-independent files in PREFIX
                            [/usr/local]
    --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                            [PREFIX]
  
  By default, 'make install' will install all the files in
  '/usr/local/bin', '/usr/local/lib' etc.  You can specify
  an installation prefix other than '/usr/local' using '--prefix',
  for instance '--prefix=$HOME'.
  
  For better control, use the options below.

    --bindir=DIR            user executables [EPREFIX/bin]
    --sbindir=DIR           system admin executables [EPREFIX/sbin]

    --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
    --libdir=DIR            object code libraries [EPREFIX/lib]
    --includedir=DIR        C header files [PREFIX/include]
    --oldincludedir=DIR     C header files for non-gcc [/usr/include]
    --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
    --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
    --infodir=DIR           info documentation [DATAROOTDIR/info]
    --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]

                            specified (default: do not rely on any group used

    --without-gmp           do not use the GNU MP library for arbitrary

  Some influential environment variables:
    CC          C compiler command
    CFLAGS      C compiler flags
    LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
                nonstandard directory <lib dir>
    LIBS        libraries to pass to the linker, e.g. -l<library>
    CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
                you have headers in a nonstandard directory <include dir>
    CPP         C preprocessor
    YACC        The "Yet Another C Compiler" implementation to use. Defaults to
                'bison -y'. Values other than 'bison -y' will most likely break
                on most systems.
    YFLAGS      YFLAGS contains the list arguments that will be passed by
                default to Bison. This script will default YFLAGS to the empty
                string to avoid a default value of '-d' given by some make
                applications.
    DEFAULT_POSIX2_VERSION
                POSIX version to default to; see 'config.hin'.
  
  Use these variables to override the choices made by 'configure' or to help
  it to find libraries and programs with nonstandard names/locations.
