1255 \`configure' configures this package to adapt to many kinds of systems.
1256
1257 Usage: $0 [OPTION]... [VAR=VALUE]...
1258
1259 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1260 VAR=VALUE.  See below for descriptions of some of the useful variables.
1261
1262 Defaults for the options are specified in brackets.
1263
1264 Configuration:
1265   -h, --help              display this help and exit
1266       --help=short        display options specific to this package
1267       --help=recursive    display the short help of all the included packages
1268   -V, --version           display version information and exit
1269   -q, --quiet, --silent   do not print \`checking ...' messages
1270       --cache-file=FILE   cache test results in FILE [disabled]
1271   -C, --config-cache      alias for \`--cache-file=config.cache'
1272   -n, --no-create         do not create output files
1273       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1274
1275 Installation directories:
1276   --prefix=PREFIX         install architecture-independent files in PREFIX
1277                           [$ac_default_prefix]
1278   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1279                           [PREFIX]
1280
1281 By default, \`make install' will install all the files in
1282 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1283 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1284 for instance \`--prefix=\$HOME'.
1285
1286 For better control, use the options below.

1343 Some influential environment variables:
1344   CC          C compiler command
1345   CFLAGS      C compiler flags
1346   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1347               nonstandard directory <lib dir>
1348   LIBS        libraries to pass to the linker, e.g. -l<library>
1349   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1350               you have headers in a nonstandard directory <include dir>
1351   CPP         C preprocessor
1352   XMKMF       Path to xmkmf, Makefile generator for X Window System
1353
1354 Use these variables to override the choices made by `configure' or to help
1355 it to find libraries and programs with nonstandard names/locations.
