1308 \`configure' configures this package to adapt to many kinds of systems.

1310 Usage: $0 [OPTION]... [VAR=VALUE]...
1311
1312 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1313 VAR=VALUE.  See below for descriptions of some of the useful variables.
1314
1315 Defaults for the options are specified in brackets.
1316
1317 Configuration:
1318   -h, --help              display this help and exit
1319       --help=short        display options specific to this package
1320       --help=recursive    display the short help of all the included packages
1321   -V, --version           display version information and exit
1322   -q, --quiet, --silent   do not print \`checking ...' messages
1323       --cache-file=FILE   cache test results in FILE [disabled]
1324   -C, --config-cache      alias for \`--cache-file=config.cache'
1325   -n, --no-create         do not create output files
1326       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1327
1328 Installation directories:
1329   --prefix=PREFIX         install architecture-independent files in PREFIX
1330                           [$ac_default_prefix]
1331   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1332                           [PREFIX]
1333
1334 By default, \`make install' will install all the files in
1335 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1336 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1337 for instance \`--prefix=\$HOME'.
1338
1339 For better control, use the options below.

1423 Some influential environment variables:
1424   CC          C compiler command
1425   CFLAGS      C compiler flags
1426   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1427               nonstandard directory <lib dir>
1428   LIBS        libraries to pass to the linker, e.g. -l<library>
1429   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1430               you have headers in a nonstandard directory <include dir>
1431   CPP         C preprocessor
1432   YACC        The `Yet Another Compiler Compiler' implementation to use.
1433               Defaults to the first program found out of: `bison -y', `byacc',
1434               `yacc'.
1435   YFLAGS      The list of arguments that will be passed by default to $YACC.
1436               This script will default YFLAGS to the empty string to avoid a
1437               default value of `-d' given by some make applications.
1438
1439 Use these variables to override the choices made by `configure' or to help
1440 it to find libraries and programs with nonstandard names/locations.
