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

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

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

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

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

 804 Optional Packages:
 805   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
 806   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
 807   --with-pty-mode=mode    default mode for ptys
 808   --with-pty-group=group  default group for ptys

 810 Some influential environment variables:
 811   CC          C compiler command
 812   CFLAGS      C compiler flags
 813   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 814               nonstandard directory <lib dir>
 815   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
 816               headers in a nonstandard directory <include dir>
 817   CPP         C preprocessor
 818
 819 Use these variables to override the choices made by `configure' or to help
 820 it to find libraries and programs with nonstandard names/locations.
