1262 \`configure' configures readline 6.3 to adapt to many kinds of systems.
1263
1264 Usage: $0 [OPTION]... [VAR=VALUE]...
1265
1266 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1267 VAR=VALUE.  See below for descriptions of some of the useful variables.
1268
1269 Defaults for the options are specified in brackets.
1270
1271 Configuration:
1272   -h, --help              display this help and exit
1273       --help=short        display options specific to this package
1274       --help=recursive    display the short help of all the included packages
1275   -V, --version           display version information and exit
1276   -q, --quiet, --silent   do not print \`checking ...' messages
1277       --cache-file=FILE   cache test results in FILE [disabled]
1278   -C, --config-cache      alias for \`--cache-file=config.cache'
1279   -n, --no-create         do not create output files
1280       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1281
1282 Installation directories:
1283   --prefix=PREFIX         install architecture-independent files in PREFIX
1284                           [$ac_default_prefix]
1285   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1286                           [PREFIX]
1287
1288 By default, \`make install' will install all the files in
1289 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1290 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1291 for instance \`--prefix=\$HOME'.
1292
1293 For better control, use the options below.

1347 Some influential environment variables:
1348   CC          C compiler command
1349   CFLAGS      C compiler flags
1350   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1351               nonstandard directory <lib dir>
1352   LIBS        libraries to pass to the linker, e.g. -l<library>
1353   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1354               you have headers in a nonstandard directory <include dir>
1355   CPP         C preprocessor
1356
1357 Use these variables to override the choices made by `configure' or to help
1358 it to find libraries and programs with nonstandard names/locations.
