1602 \`configure' configures zfs 0.7.3 to adapt to many kinds of systems.
1603
1604 Usage: $0 [OPTION]... [VAR=VALUE]...
1605
1606 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1607 VAR=VALUE.  See below for descriptions of some of the useful variables.
1608
1609 Defaults for the options are specified in brackets.
1610
1611 Configuration:
1612   -h, --help              display this help and exit
1613       --help=short        display options specific to this package
1614       --help=recursive    display the short help of all the included packages
1615   -V, --version           display version information and exit
1616   -q, --quiet, --silent   do not print \`checking...' messages
1617       --cache-file=FILE   cache test results in FILE [disabled]
1618   -C, --config-cache      alias for \`--cache-file=config.cache'
1619   -n, --no-create         do not create output files
1620       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1621
1622 Installation directories:
1623   --prefix=PREFIX         install architecture-independent files in PREFIX
1624                           [$ac_default_prefix]
1625   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1626                           [PREFIX]
1627
1628 By default, \`make install' will install all the files in
1629 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1630 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1631 for instance \`--prefix=\$HOME'.
1632
1633 For better control, use the options below.
