1513 \`configure' configures this package to adapt to many kinds of systems.
1514
1515 Usage: $0 [OPTION]... [VAR=VALUE]...
1516
1517 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1518 VAR=VALUE.  See below for descriptions of some of the useful variables.
1519
1520 Defaults for the options are specified in brackets.
1521
1522 Configuration:
1523   -h, --help              display this help and exit
1524       --help=short        display options specific to this package
1525       --help=recursive    display the short help of all the included packages
1526   -V, --version           display version information and exit
1527   -q, --quiet, --silent   do not print \`checking...' messages
1528       --cache-file=FILE   cache test results in FILE [disabled]
1529   -C, --config-cache      alias for \`--cache-file=config.cache'
1530   -n, --no-create         do not create output files
1531       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1532
1533 Installation directories:
1534   --prefix=PREFIX         install architecture-independent files in PREFIX
1535                           [$ac_default_prefix]
1536   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1537                           [PREFIX]
1538
1539 By default, \`make install' will install all the files in
1540 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1541 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1542 for instance \`--prefix=\$HOME'.
