1268 \`configure' configures this package to adapt to many kinds of systems.

1270 Usage: $0 [OPTION]... [VAR=VALUE]...
1271
1272 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1273 VAR=VALUE.  See below for descriptions of some of the useful variables.
1274
1275 Defaults for the options are specified in brackets.
1276
1277 Configuration:
1278   -h, --help              display this help and exit
1279       --help=short        display options specific to this package
1280       --help=recursive    display the short help of all the included packages
1281   -V, --version           display version information and exit
1282   -q, --quiet, --silent   do not print \`checking ...' messages
1283       --cache-file=FILE   cache test results in FILE [disabled]
1284   -C, --config-cache      alias for \`--cache-file=config.cache'
1285   -n, --no-create         do not create output files
1286       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1287
1288 Installation directories:
1289   --prefix=PREFIX         install architecture-independent files in PREFIX
1290                           [$ac_default_prefix]
1291   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1292                           [PREFIX]
1293
1294 By default, \`make install' will install all the files in
1295 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1296 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1297 for instance \`--prefix=\$HOME'.
1298
1299 For better control, use the options below.

1364 Some influential environment variables:
1365   CC          C compiler command
1366   CFLAGS      C compiler flags
1367   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1368               nonstandard directory <lib dir>
1369   LIBS        libraries to pass to the linker, e.g. -l<library>
1370   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1371               you have headers in a nonstandard directory <include dir>
1372   CPP         C preprocessor
1373   PKG_CONFIG  path to pkg-config utility
1374   PKG_CONFIG_PATH
1375               directories to add to pkg-config's search path
1376   PKG_CONFIG_LIBDIR
1377               path overriding pkg-config's built-in search path
1378   EXT2FS_CFLAGS
1379               C compiler flags for EXT2FS, overriding pkg-config
1380   EXT2FS_LIBS linker flags for EXT2FS, overriding pkg-config
1381
1382 Use these variables to override the choices made by `configure' or to help
1383 it to find libraries and programs with nonstandard names/locations.
