1242 \`configure' configures this package to adapt to many kinds of systems.
1243
1244 Usage: $0 [OPTION]... [VAR=VALUE]...
1245
1246 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1247 VAR=VALUE.  See below for descriptions of some of the useful variables.
1248
1249 Defaults for the options are specified in brackets.
1250
1251 Configuration:
1252   -h, --help              display this help and exit
1253       --help=short        display options specific to this package
1254       --help=recursive    display the short help of all the included packages
1255   -V, --version           display version information and exit
1256   -q, --quiet, --silent   do not print \`checking ...' messages
1257       --cache-file=FILE   cache test results in FILE [disabled]
1258   -C, --config-cache      alias for \`--cache-file=config.cache'
1259   -n, --no-create         do not create output files
1260       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1261
1262 Installation directories:
1263   --prefix=PREFIX         install architecture-independent files in PREFIX
1264                           [$ac_default_prefix]
1265   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1266                           [PREFIX]
1267
1268 By default, \`make install' will install all the files in
1269 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1270 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1271 for instance \`--prefix=\$HOME'.
1272
1273 For better control, use the options below.
1274
1275 Fine tuning of the installation directories:
1276   --bindir=DIR            user executables [EPREFIX/bin]
1277   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1306 Some influential environment variables:
1307   CC          C compiler command
1308   CFLAGS      C compiler flags
1309   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1310               nonstandard directory <lib dir>
1311   LIBS        libraries to pass to the linker, e.g. -l<library>
1312   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

1314   CPP         C preprocessor
1315
1316 Use these variables to override the choices made by `configure' or to help
1317 it to find libraries and programs with nonstandard names/locations.
