 744 \`configure' configures this package to adapt to many kinds of systems.

 746 Usage: $0 [OPTION]... [VAR=VALUE]...
 747
 748 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 749 VAR=VALUE.  See below for descriptions of some of the useful variables.
 750
 751 Defaults for the options are specified in brackets.
 752
 753 Configuration:
 754   -h, --help              display this help and exit
 755       --help=short        display options specific to this package
 756       --help=recursive    display the short help of all the included packages
 757   -V, --version           display version information and exit
 758   -q, --quiet, --silent   do not print \`checking...' messages
 759       --cache-file=FILE   cache test results in FILE [disabled]
 760   -C, --config-cache      alias for \`--cache-file=config.cache'
 761   -n, --no-create         do not create output files
 762       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 767 Installation directories:
 768   --prefix=PREFIX         install architecture-independent files in PREFIX
 769                           [$ac_default_prefix]
 770   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 771                           [PREFIX]
 772
 773 By default, \`make install' will install all the files in
 774 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 775 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 776 for instance \`--prefix=\$HOME'.
 777
 778 For better control, use the options below.

 780 Fine tuning of the installation directories:
 781   --bindir=DIR           user executables [EPREFIX/bin]
 782   --sbindir=DIR          system admin executables [EPREFIX/sbin]
 783   --libexecdir=DIR       program executables [EPREFIX/libexec]

 789   --includedir=DIR       C header files [PREFIX/include]
 790   --oldincludedir=DIR    C header files for non-gcc [/usr/include]

 803 Optional Packages:
 804   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
 805   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
 806   --with-pty-mode=mode    default mode for ptys
 807   --with-pty-group=group  default group for ptys
 808
 809 Some influential environment variables:
 810   CC          C compiler command
 811   CFLAGS      C compiler flags
 812   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 813               nonstandard directory <lib dir>
 814   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
 815               headers in a nonstandard directory <include dir>
 816   CPP         C preprocessor
 817
 818 Use these variables to override the choices made by `configure' or to help
 819 it to find libraries and programs with nonstandard names/locations.
