1242
1243	To assign environment variables (e.g., CC, CFLAGS...), specify them as
1244	VAR=VALUE. See below for descriptions of some of the useful variables.
1245
1246	Defaults for the options are specified in brackets.
1247
1248	Configuration:
1249	-h, --help display this help and exit
1250	--help=short display options specific to this package
1251	--help=recursive display the short help of all the included packages
1252	-V, --version display version information and exit
1253	-q, --quiet, --silent do not print \`checking ...' messages
1254	--cache-file=FILE cache test results in FILE [disabled]
1255	-C, --config-cache alias for \`--cache-file=config.cache'
1256	-n, --no-create do not create output files

1259	Installation directories:

1267	an installation prefix other than \`$ac_default_prefix' using \`--prefix',
