  1411 \`configure' configures this package to adapt to many kinds of systems.
  1413 Usage: $0 [OPTION]... [VAR=VALUE]...
  1415 To assign environment variables (e.g., CC, CFLAGS...), specify them as
  1416 VAR=VALUE.  See below for descriptions of some of the useful variables.
  1418 Defaults for the options are specified in brackets.
  1420 Configuration:
  1421   -h, --help              display this help and exit
  1422       --help=short        display options specific to this package
  1423       --help=recursive    display the short help of all the included packages
  1424   -V, --version           display version information and exit
  1425   -q, --quiet, --silent   do not print \`checking...' messages
  1426       --cache-file=FILE   cache test results in FILE [disabled]
  1427   -C, --config-cache      alias for \`--cache-file=config.cache'
  1428   -n, --no-create         do not create output files
  1429       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
  1431 Installation directories:
  1432   --prefix=PREFIX         install architecture-independent files in PREFIX
  1433                           [$ac_default_prefix]
  1434   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
  1435                           [PREFIX]
  1437 By default, \`make install' will install all the files in
