1427 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1428
1429 Usage: $0 [OPTION]... [VAR=VALUE]...
1430
1431 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1432 VAR=VALUE.  See below for descriptions of some of the useful variables.
1433
1434 Defaults for the options are specified in brackets.
1435
1436 Configuration:
1437   -h, --help              display this help and exit
1438       --help=short        display options specific to this package
1439       --help=recursive    display the short help of all the included packages
1440   -V, --version           display version information and exit
1441   -q, --quiet, --silent   do not print \`checking...' messages
1442       --cache-file=FILE   cache test results in FILE [disabled]
1443   -C, --config-cache      alias for \`--cache-file=config.cache'
1444   -n, --no-create         do not create output files
1445       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1446
1447 Installation directories:
1448   --prefix=PREFIX         install architecture-independent files in PREFIX
1449                           [$ac_default_prefix]
1450   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1451                           [PREFIX]
1452
1453 By default, \`make install' will install all the files in
1454 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1455 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1456 for instance \`--prefix=\$HOME'.
1457
1458 For better control, use the options below.

1461   --bindir=DIR            user executables [EPREFIX/bin]

1584   LIBS        libraries to pass to the linker, e.g. -l<library>
1585   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1586               you have headers in a nonstandard directory <include dir>

1588   CXXFLAGS    C++ compiler flags
1589   CPP         C preprocessor
1590   CXXCPP      C++ preprocessor

1592               `c++filt', `gc++filt' on PATH.

1594 Use these variables to override the choices made by `configure' or to help
1595 it to find libraries and programs with nonstandard names/locations.
