|  | Usage: $0 [OPTION]... [VAR=VALUE]... | 
|  |  | 
|  | To assign environment variables (e.g., CC, CFLAGS...), specify them as | 
|  | VAR=VALUE.  See below for descriptions of some of the useful variables. | 
|  |  | 
|  | Defaults for the options are specified in brackets. | 
|  |  | 
|  | Configuration: | 
|  | -h, --help              display this help and exit | 
|  | --help=short        display options specific to this package | 
|  | --help=recursive    display the short help of all the included packages | 
|  | -V, --version           display version information and exit | 
|  | -q, --quiet, --silent   do not print \`checking ...' messages | 
|  | --cache-file=FILE   cache test results in FILE [disabled] | 
|  | -C, --config-cache      alias for \`--cache-file=config.cache' |

|  | By default, \`make install' will install all the files in | 
|  | \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify | 
|  | an installation prefix other than \`$ac_default_prefix' using \`--prefix', |
