1250 \`configure' configures readline 7.0 to adapt to many kinds of systems.
1251
1252 Usage: $0 [OPTION]... [VAR=VALUE]...
1253
1254 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1255 VAR=VALUE.  See below for descriptions of some of the useful variables.
1256
1257 Defaults for the options are specified in brackets.
1258
1259 Configuration:
1260   -h, --help              display this help and exit
1261       --help=short        display options specific to this package
1262       --help=recursive    display the short help of all the included packages
1263   -V, --version           display version information and exit
1264   -q, --quiet, --silent   do not print \`checking...' messages
1265       --cache-file=FILE   cache test results in FILE [disabled]
1266   -C, --config-cache      alias for \`--cache-file=config.cache'
1267   -n, --no-create         do not create output files
1268       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1269
1270 Installation directories:
1271   --prefix=PREFIX         install architecture-independent files in PREFIX
1272                           [$ac_default_prefix]
1273   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1274                           [PREFIX]
1275
1276 By default, \`make install' will install all the files in
1277 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1278 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1279 for instance \`--prefix=\$HOME'.
1280
1281 For better control, use the options below.

1335 Some influential environment variables:
1336   CC          C compiler command
1337   CFLAGS      C compiler flags
1338   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1339               nonstandard directory <lib dir>
1340   LIBS        libraries to pass to the linker, e.g. -l<library>
1341   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1342               you have headers in a nonstandard directory <include dir>
1343   CPP         C preprocessor
1344
1345 Use these variables to override the choices made by `configure' or to help
1346 it to find libraries and programs with nonstandard names/locations.
