1532 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1533
1534 Usage: $0 [OPTION]... [VAR=VALUE]...
1535
1536 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1537 VAR=VALUE.  See below for descriptions of some of the useful variables.
1538
1539 Defaults for the options are specified in brackets.
1540
1541 Configuration:
1542   -h, --help              display this help and exit
1543       --help=short        display options specific to this package
1544       --help=recursive    display the short help of all the included packages
1545   -V, --version           display version information and exit
1546   -q, --quiet, --silent   do not print \`checking ...' messages
1547       --cache-file=FILE   cache test results in FILE [disabled]
1548   -C, --config-cache      alias for \`--cache-file=config.cache'
1549   -n, --no-create         do not create output files
1550       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1551
1552 Installation directories:
1553   --prefix=PREFIX         install architecture-independent files in PREFIX
1554                           [$ac_default_prefix]
1555   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1556                           [PREFIX]
1557
1558 By default, \`make install' will install all the files in
1559 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1560 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1561 for instance \`--prefix=\$HOME'.
1562
1563 For better control, use the options below.
