1311 \`configure' configures nettle 2.7.1 to adapt to many kinds of systems.
1312
1313 Usage: $0 [OPTION]... [VAR=VALUE]...
1314
1315 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1316 VAR=VALUE.  See below for descriptions of some of the useful variables.
1317
1318 Defaults for the options are specified in brackets.
1319
1320 Configuration:
1321   -h, --help              display this help and exit
1322       --help=short        display options specific to this package
1323       --help=recursive    display the short help of all the included packages
1324   -V, --version           display version information and exit
1325   -q, --quiet, --silent   do not print \`checking ...' messages
1326       --cache-file=FILE   cache test results in FILE [disabled]
1327   -C, --config-cache      alias for \`--cache-file=config.cache'
1328   -n, --no-create         do not create output files
1329       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1330
1331 Installation directories:
1332   --prefix=PREFIX         install architecture-independent files in PREFIX
1333                           [$ac_default_prefix]
1334   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1335                           [PREFIX]
1336
1337 By default, \`make install' will install all the files in
1338 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1339 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1340 for instance \`--prefix=\$HOME'.
1341
1342 For better control, use the options below.

1345   --bindir=DIR            user executables [EPREFIX/bin]
