 783 Usage: $0 [OPTION]... [VAR=VALUE]...
 784
 785 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 786 VAR=VALUE.  See below for descriptions of some of the useful variables.
 787
 788 Defaults for the options are specified in brackets.
 789
 790 Configuration:
 791   -h, --help              display this help and exit
 792       --help=short        display options specific to this package
 793       --help=recursive    display the short help of all the included packages
 794   -V, --version           display version information and exit
 795   -q, --quiet, --silent   do not print \`checking...' messages
 796       --cache-file=FILE   cache test results in FILE [disabled]
 797   -C, --config-cache      alias for \`--cache-file=config.cache'
 798   -n, --no-create         do not create output files
 799       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 804 Installation directories:

 808                           [PREFIX]
 809
 810 By default, \`make install' will install all the files in
 811 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 812 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 813 for instance \`--prefix=\$HOME'.
 814
 815 For better control, use the options below.

 817 Fine tuning of the installation directories:
 818   --bindir=DIR           user executables [EPREFIX/bin]
 819   --sbindir=DIR          system admin executables [EPREFIX/sbin]

 840 Optional Features:

 842   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
 843   --disable-socket-dir    disable system wide socket-dir and use ~/.screen instead

 850 Optional Packages:
 851   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
 852   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
 853   --with-socket-dir=path  where to put the per-user sockets
 854   --with-pty-mode=mode    default mode for ptys
 855   --with-pty-group=group  default group for ptys
 856   --with-sys-screenrc=path  where to put the global screenrc file

 858 Some influential environment variables:
 859   CC          C compiler command
 860   CFLAGS      C compiler flags
 861   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 862               nonstandard directory <lib dir>
 863   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
 864               headers in a nonstandard directory <include dir>
 865   CPP         C preprocessor
 866
 867 Use these variables to override the choices made by `configure' or to help
 868 it to find libraries and programs with nonstandard names/locations.
