1306 \`configure' configures this package to adapt to many kinds of systems.
1307
1308 Usage: $0 [OPTION]... [VAR=VALUE]...
1309
1310 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1311 VAR=VALUE.  See below for descriptions of some of the useful variables.
1312
1313 Defaults for the options are specified in brackets.
1314
1315 Configuration:
1316   -h, --help              display this help and exit
1317       --help=short        display options specific to this package
1318       --help=recursive    display the short help of all the included packages
1319   -V, --version           display version information and exit
1320   -q, --quiet, --silent   do not print \`checking ...' messages
1321       --cache-file=FILE   cache test results in FILE [disabled]
1322   -C, --config-cache      alias for \`--cache-file=config.cache'
1323   -n, --no-create         do not create output files
1324       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1325
1326 Installation directories:
1327   --prefix=PREFIX         install architecture-independent files in PREFIX
1328                           [$ac_default_prefix]
1329   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1330                           [PREFIX]
1331
1332 By default, \`make install' will install all the files in
1333 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1334 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1335 for instance \`--prefix=\$HOME'.
1336
1337 For better control, use the options below.

1427 Some influential environment variables:
1428   CC          C compiler command
1429   CFLAGS      C compiler flags
1430   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1431               nonstandard directory <lib dir>
1432   LIBS        libraries to pass to the linker, e.g. -l<library>
1433   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1434               you have headers in a nonstandard directory <include dir>
1435   CPP         C preprocessor
1436
1437 Use these variables to override the choices made by `configure' or to help
1438 it to find libraries and programs with nonstandard names/locations.
