1572 \`configure' configures this package to adapt to many kinds of systems.

1574 Usage: $0 [OPTION]... [VAR=VALUE]...
1575
1576 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1577 VAR=VALUE.  See below for descriptions of some of the useful variables.
1578
1579 Defaults for the options are specified in brackets.
1580
1581 Configuration:
1582   -h, --help              display this help and exit
1583       --help=short        display options specific to this package
1584       --help=recursive    display the short help of all the included packages
1585   -V, --version           display version information and exit
1586   -q, --quiet, --silent   do not print \`checking ...' messages
1587       --cache-file=FILE   cache test results in FILE [disabled]
1588   -C, --config-cache      alias for \`--cache-file=config.cache'
1589   -n, --no-create         do not create output files
1590       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1591
1592 Installation directories:
1593   --prefix=PREFIX         install architecture-independent files in PREFIX
1594                           [$ac_default_prefix]
1595   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1596                           [PREFIX]
1597
1598 By default, \`make install' will install all the files in
1599 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1600 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1601 for instance \`--prefix=\$HOME'.

1835               nonstandard directory <lib dir>
1836   LIBS        libraries to pass to the linker, e.g. -l<library>
1837   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
