1302 \`configure' configures this package to adapt to many kinds of systems.
1303
1304 Usage: $0 [OPTION]... [VAR=VALUE]...
1305
1306 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1307 VAR=VALUE.  See below for descriptions of some of the useful variables.
1308
1309 Defaults for the options are specified in brackets.
1310
1311 Configuration:
1312   -h, --help              display this help and exit
1313       --help=short        display options specific to this package
1314       --help=recursive    display the short help of all the included packages
1315   -V, --version           display version information and exit
1316   -q, --quiet, --silent   do not print \`checking ...' messages
1317       --cache-file=FILE   cache test results in FILE [disabled]
1318   -C, --config-cache      alias for \`--cache-file=config.cache'
1319   -n, --no-create         do not create output files
1320       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1321
1322 Installation directories:
1323   --prefix=PREFIX         install architecture-independent files in PREFIX
1324                           [$ac_default_prefix]
1325   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1326                           [PREFIX]
1327
1328 By default, \`make install' will install all the files in
1329 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1330 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1331 for instance \`--prefix=\$HOME'.
1332
1333 For better control, use the options below.

1415 Some influential environment variables:
1416   CC          C compiler command
1417   CFLAGS      C compiler flags
1418   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1419               nonstandard directory <lib dir>
1420   LIBS        libraries to pass to the linker, e.g. -l<library>
1421   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1422               you have headers in a nonstandard directory <include dir>
1423   CPP         C preprocessor
1424
1425 Use these variables to override the choices made by `configure' or to help
1426 it to find libraries and programs with nonstandard names/locations.
