1277 \`configure' configures readline 7.0 to adapt to many kinds of systems.
1278
1279 Usage: $0 [OPTION]... [VAR=VALUE]...
1280
1281 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1282 VAR=VALUE.  See below for descriptions of some of the useful variables.
1283
1284 Defaults for the options are specified in brackets.
1285
1286 Configuration:
1287   -h, --help              display this help and exit
1288       --help=short        display options specific to this package
1289       --help=recursive    display the short help of all the included packages
1290   -V, --version           display version information and exit
1291   -q, --quiet, --silent   do not print \`checking ...' messages
1292       --cache-file=FILE   cache test results in FILE [disabled]
1293   -C, --config-cache      alias for \`--cache-file=config.cache'
1294   -n, --no-create         do not create output files
1295       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1296
1297 Installation directories:
1298   --prefix=PREFIX         install architecture-independent files in PREFIX
1299                           [$ac_default_prefix]
1300   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1301                           [PREFIX]
1302
1303 By default, \`make install' will install all the files in
1304 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1305 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1306 for instance \`--prefix=\$HOME'.
1307
1308 For better control, use the options below.

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