1249 \`configure' configures readline 6.2 to adapt to many kinds of systems.
1250
1251 Usage: $0 [OPTION]... [VAR=VALUE]...
1252
1253 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1254 VAR=VALUE.  See below for descriptions of some of the useful variables.
1255
1256 Defaults for the options are specified in brackets.
1257
1258 Configuration:
1259   -h, --help              display this help and exit
1260       --help=short        display options specific to this package
1261       --help=recursive    display the short help of all the included packages
1262   -V, --version           display version information and exit
1263   -q, --quiet, --silent   do not print \`checking...' messages
1264       --cache-file=FILE   cache test results in FILE [disabled]
1265   -C, --config-cache      alias for \`--cache-file=config.cache'
1266   -n, --no-create         do not create output files
1267       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1268
1269 Installation directories:
1270   --prefix=PREFIX         install architecture-independent files in PREFIX
1271                           [$ac_default_prefix]
1272   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1273                           [PREFIX]
1274
1275 By default, \`make install' will install all the files in
1276 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1277 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1278 for instance \`--prefix=\$HOME'.
1279
1280 For better control, use the options below.

1282 Fine tuning of the installation directories:

1333 Some influential environment variables:
1334   CC          C compiler command
1335   CFLAGS      C compiler flags
1336   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1337               nonstandard directory <lib dir>
1338   LIBS        libraries to pass to the linker, e.g. -l<library>
1339   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1340               you have headers in a nonstandard directory <include dir>
1341   CPP         C preprocessor
1342
1343 Use these variables to override the choices made by `configure' or to help
1344 it to find libraries and programs with nonstandard names/locations.
