1476 \`configure' configures this package to adapt to many kinds of systems.
1478 Usage: $0 [OPTION]... [VAR=VALUE]...
1480 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1481 VAR=VALUE. See below for descriptions of some of the useful variables.
1483 Defaults for the options are specified in brackets.
1486 -h, --help display this help and exit
1487 --help=short display options specific to this package
1488 --help=recursive display the short help of all the included packages
1489 -V, --version display version information and exit
1490 -q, --quiet, --silent do not print \`checking...' messages
1491 --cache-file=FILE cache test results in FILE [disabled]
1492 -C, --config-cache alias for \`--cache-file=config.cache'
1493 -n, --no-create do not create output files
1494 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1496 Installation directories:
1497 --prefix=PREFIX install architecture-independent files in PREFIX
1498 [$ac_default_prefix]
1499 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1502 By default, \`make install' will install all the files in
1503 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1504 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1505 for instance \`--prefix=\$HOME'.
1507 For better control, use the options below.
