1497 \`configure' configures this package to adapt to many kinds of systems.

1499 Usage: $0 [OPTION]... [VAR=VALUE]...
1500
1501 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1502 VAR=VALUE.  See below for descriptions of some of the useful variables.
1503
1504 Defaults for the options are specified in brackets.
1505
1506 Configuration:
1507   -h, --help              display this help and exit
1508       --help=short        display options specific to this package
1509       --help=recursive    display the short help of all the included packages
1510   -V, --version           display version information and exit
1511   -q, --quiet, --silent   do not print \`checking...' messages
1512       --cache-file=FILE   cache test results in FILE [disabled]
1513   -C, --config-cache      alias for \`--cache-file=config.cache'
1514   -n, --no-create         do not create output files
1515       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1516
1517 Installation directories:
1518   --prefix=PREFIX         install architecture-independent files in PREFIX
1519                           [$ac_default_prefix]
1520   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1521                           [PREFIX]
1522
1523 By default, \`make install' will install all the files in
1524 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1525 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1526 for instance \`--prefix=\$HOME'.
1527
1528 For better control, use the options below.
