 1662 \`configure' configures vips 8.12.1 to adapt to many kinds of systems.
 1663 
 1664 Usage: $0 [OPTION]... [VAR=VALUE]...
 1665 
 1666 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1667 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1668 
 1669 Defaults for the options are specified in brackets.
 1670 
 1671 Configuration:
 1672   -h, --help              display this help and exit
 1673       --help=short        display options specific to this package
 1674       --help=recursive    display the short help of all the included packages
 1675   -V, --version           display version information and exit
 1676   -q, --quiet, --silent   do not print \`checking ...' messages
 1677       --cache-file=FILE   cache test results in FILE [disabled]
 1678   -C, --config-cache      alias for \`--cache-file=config.cache'
 1679   -n, --no-create         do not create output files
 1680       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1681 
 1682 Installation directories:
 1683   --prefix=PREFIX         install architecture-independent files in PREFIX
 1684                           [$ac_default_prefix]
 1685   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1686                           [PREFIX]
 1687 
 1688 By default, \`make install' will install all the files in
 1689 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1690 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1691 for instance \`--prefix=\$HOME'.
 1692 
 1693 For better control, use the options below.

 3653 on the command line, even when the '-f' option is present.  This is contrary
 3654 to the behaviour of most rm programs out there, and not conforming with
 3655 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 3656
