 609 Usage: $0 [OPTION]... [VAR=VALUE]...
 610
 611 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 612 VAR=VALUE.  See below for descriptions of some of the useful variables.
 613
 614 Defaults for the options are specified in brackets.
 615
 616 Configuration:
 617   -h, --help              display this help and exit
 618       --help=short        display options specific to this package
 619       --help=recursive    display the short help of all the included packages
 620   -V, --version           display version information and exit
 621   -q, --quiet, --silent   do not print \`checking...' messages
 622       --cache-file=FILE   cache test results in FILE [disabled]
 623   -C, --config-cache      alias for \`--cache-file=config.cache'
 624   -n, --no-create         do not create output files
 625       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 634                           [PREFIX]
 635
 636 By default, \`make install' will install all the files in
 637 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 638 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 639 for instance \`--prefix=\$HOME'.
 640
 641 For better control, use the options below.

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

 681   --with-curses           use the curses library instead of the termcap

 684 Some influential environment variables:
 685   CC          C compiler command
 686   CFLAGS      C compiler flags
 687   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 688               nonstandard directory <lib dir>
 689   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
 690               headers in a nonstandard directory <include dir>
 691   CPP         C preprocessor
 692
 693 Use these variables to override the choices made by `configure' or to help
 694 it to find libraries and programs with nonstandard names/locations.
