1255	Usage: $0 [OPTION]... [VAR=VALUE]...
1256
1257	To assign environment variables (e.g., CC, CFLAGS...), specify them as
1258	VAR=VALUE. See below for descriptions of some of the useful variables.
1259
1260	Defaults for the options are specified in brackets.
1261
1262	Configuration:
1263	-h, --help display this help and exit
1264	--help=short display options specific to this package
1265	--help=recursive display the short help of all the included packages
1266	-V, --version display version information and exit
1267	-q, --quiet, --silent do not print \`checking ...' messages
1268	--cache-file=FILE cache test results in FILE [disabled]
1269	-C, --config-cache alias for \`--cache-file=config.cache'
1270	-n, --no-create do not create output files

1273	Installation directories:

1281	an installation prefix other than \`$ac_default_prefix' using \`--prefix',
