  1372 \`configure' configures this package to adapt to many kinds of systems.
  1374 Usage: $0 [OPTION]... [VAR=VALUE]...
  1376 To assign environment variables (e.g., CC, CFLAGS...), specify them as
  1377 VAR=VALUE.  See below for descriptions of some of the useful variables.
  1379 Defaults for the options are specified in brackets.
  1381 Configuration:
  1382   -h, --help              display this help and exit
  1383       --help=short        display options specific to this package
  1384       --help=recursive    display the short help of all the included packages
  1385   -V, --version           display version information and exit
  1386   -q, --quiet, --silent   do not print \`checking...' messages
  1387       --cache-file=FILE   cache test results in FILE [disabled]
  1388   -C, --config-cache      alias for \`--cache-file=config.cache'
  1389   -n, --no-create         do not create output files
  1390       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
  1392 Installation directories:
  1393   --prefix=PREFIX         install architecture-independent files in PREFIX
  1394 			  [$ac_default_prefix]
  1395   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
  1396 			  [PREFIX]
  1398 By default, \`make install' will install all the files in
  1399 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
  1400 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
  1401 for instance \`--prefix=\$HOME'.
