1412   -h, --help              display this help and exit
1413       --help=short        display options specific to this package
1414       --help=recursive    display the short help of all the included packages
1415   -V, --version           display version information and exit
1416   -q, --quiet, --silent   do not print \`checking...' messages
1417       --cache-file=FILE   cache test results in FILE [disabled]
1418   -C, --config-cache      alias for \`--cache-file=config.cache'
1419   -n, --no-create         do not create output files
1420       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1421
1422 Installation directories:
1423   --prefix=PREFIX         install architecture-independent files in PREFIX
1424                           [$ac_default_prefix]
1425   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1426                           [PREFIX]
1427
1428 By default, \`make install' will install all the files in
1429 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1430 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1431 for instance \`--prefix=\$HOME'.

1433 For better control, use the options below.

1554   CFLAGS      C compiler flags
1555   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1556               nonstandard directory <lib dir>
1557   LIBS        libraries to pass to the linker, e.g. -l<library>
1558   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1559               you have headers in a nonstandard directory <include dir>
1560   CXX         C++ compiler command
1561   CXXFLAGS    C++ compiler flags
1562   CPP         C preprocessor
1563   CXXCPP      C++ preprocessor

1565               `c++filt', `gc++filt' on PATH.
1566
1567 Use these variables to override the choices made by `configure' or to help
1568 it to find libraries and programs with nonstandard names/locations.
