1231 \`configure' configures this package to adapt to many kinds of systems.
1232
1233 Usage: $0 [OPTION]... [VAR=VALUE]...
1234
1235 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1236 VAR=VALUE.  See below for descriptions of some of the useful variables.
1237
1238 Defaults for the options are specified in brackets.
1239
1240 Configuration:
1241   -h, --help              display this help and exit
1242       --help=short        display options specific to this package
1243       --help=recursive    display the short help of all the included packages
1244   -V, --version           display version information and exit
1245   -q, --quiet, --silent   do not print \`checking ...' messages
1246       --cache-file=FILE   cache test results in FILE [disabled]
1247   -C, --config-cache      alias for \`--cache-file=config.cache'
1248   -n, --no-create         do not create output files
1249       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1250
1251 Installation directories:
1252   --prefix=PREFIX         install architecture-independent files in PREFIX
1253                           [$ac_default_prefix]
1254   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1255                           [PREFIX]
1256
1257 By default, \`make install' will install all the files in
1258 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1259 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1260 for instance \`--prefix=\$HOME'.
1261
1262 For better control, use the options below.
1263
1264 Fine tuning of the installation directories:
1265   --bindir=DIR            user executables [EPREFIX/bin]
1266   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1294 Optional Packages:
1295   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1296   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1297   --with-pty-mode=mode    default mode for ptys
1298   --with-pty-group=group  default group for ptys
1299
1300 Some influential environment variables:
1301   CC          C compiler command
1302   CFLAGS      C compiler flags
1303   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1304               nonstandard directory <lib dir>
1305   LIBS        libraries to pass to the linker, e.g. -l<library>
1306   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1307               you have headers in a nonstandard directory <include dir>
1308   CPP         C preprocessor
1309
1310 Use these variables to override the choices made by `configure' or to help
1311 it to find libraries and programs with nonstandard names/locations.
