1510 \`configure' configures this package to adapt to many kinds of systems.

1512 Usage: $0 [OPTION]... [VAR=VALUE]...
1513
1514 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1515 VAR=VALUE.  See below for descriptions of some of the useful variables.
1516
1517 Defaults for the options are specified in brackets.
1518
1519 Configuration:
1520   -h, --help              display this help and exit
1521       --help=short        display options specific to this package
1522       --help=recursive    display the short help of all the included packages
1523   -V, --version           display version information and exit
1524   -q, --quiet, --silent   do not print \`checking...' messages
1525       --cache-file=FILE   cache test results in FILE [disabled]
1526   -C, --config-cache      alias for \`--cache-file=config.cache'
1527   -n, --no-create         do not create output files
1528       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1529
1530 Installation directories:
1531   --prefix=PREFIX         install architecture-independent files in PREFIX
1532                           [$ac_default_prefix]
1533   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1534                           [PREFIX]
1535
1536 By default, \`make install' will install all the files in
1537 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1538 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1539 for instance \`--prefix=\$HOME'.
