1279 \`configure' configures readline 6.2 to adapt to many kinds of systems.

1281 Usage: $0 [OPTION]... [VAR=VALUE]...
1282
1283 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1284 VAR=VALUE.  See below for descriptions of some of the useful variables.
1285
1286 Defaults for the options are specified in brackets.
1287
1288 Configuration:
1289   -h, --help              display this help and exit
1290       --help=short        display options specific to this package
1291       --help=recursive    display the short help of all the included packages
1292   -V, --version           display version information and exit
1293   -q, --quiet, --silent   do not print \`checking ...' messages
1294       --cache-file=FILE   cache test results in FILE [disabled]
1295   -C, --config-cache      alias for \`--cache-file=config.cache'
1296   -n, --no-create         do not create output files
1297       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1298
1299 Installation directories:
1300   --prefix=PREFIX         install architecture-independent files in PREFIX
1301                           [$ac_default_prefix]
1302   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1303                           [PREFIX]
1304
1305 By default, \`make install' will install all the files in
1306 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1307 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1308 for instance \`--prefix=\$HOME'.
1309
1310 For better control, use the options below.

1354   --disable-largefile     omit support for large files
1355
1356 Optional Packages:
1357   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1358   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1359   --with-curses           use the curses library instead of the termcap
1360                           library
1361   --with-purify           configure to postprocess with purify
1362
1363 Some influential environment variables:
1364   CC          C compiler command
1365   CFLAGS      C compiler flags
1366   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1367               nonstandard directory <lib dir>
1368   LIBS        libraries to pass to the linker, e.g. -l<library>
1369   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1370               you have headers in a nonstandard directory <include dir>
1371   CPP         C preprocessor
1372
1373 Use these variables to override the choices made by `configure' or to help
1374 it to find libraries and programs with nonstandard names/locations.
