1245	Usage: $0 [OPTION]... [VAR=VALUE]...
1246
1247	To assign environment variables (e.g., CC, CFLAGS...), specify them as
1248	VAR=VALUE. See below for descriptions of some of the useful variables.
1249
1250	Defaults for the options are specified in brackets.
1251
1252	Configuration:
1253	-h, --help display this help and exit
1254	--help=short display options specific to this package
1255	--help=recursive display the short help of all the included packages
1256	-V, --version display version information and exit
1257	-q, --quiet, --silent do not print \`checking ...' messages
1258	--cache-file=FILE cache test results in FILE [disabled]
1259	-C, --config-cache alias for \`--cache-file=config.cache'
1260	-n, --no-create do not create output files
1261	--srcdir=DIR find the sources in DIR [configure dir or \`..']

1263	Installation directories:

1266	--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX

1271	an installation prefix other than \`$ac_default_prefix' using \`--prefix',
