1260 \`configure' configures cpplib   to adapt to many kinds of systems.
1261
1262 Usage: $0 [OPTION]... [VAR=VALUE]...
1263
1264 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1265 VAR=VALUE.  See below for descriptions of some of the useful variables.
1266
1267 Defaults for the options are specified in brackets.
1268
1269 Configuration:
1270   -h, --help              display this help and exit
1271       --help=short        display options specific to this package
1272       --help=recursive    display the short help of all the included packages
1273   -V, --version           display version information and exit
1274   -q, --quiet, --silent   do not print \`checking...' messages
1275       --cache-file=FILE   cache test results in FILE [disabled]
1276   -C, --config-cache      alias for \`--cache-file=config.cache'
1277   -n, --no-create         do not create output files
1278       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1279
1280 Installation directories:
1281   --prefix=PREFIX         install architecture-independent files in PREFIX
1282                           [$ac_default_prefix]
1283   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1284                           [PREFIX]
1285
1286 By default, \`make install' will install all the files in
1287 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1288 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1289 for instance \`--prefix=\$HOME'.
1290
1291 For better control, use the options below.
