1203 \`configure' configures this package to adapt to many kinds of systems.
1204
1205 Usage: $0 [OPTION]... [VAR=VALUE]...
1206
1207 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1208 VAR=VALUE.  See below for descriptions of some of the useful variables.
1209
1210 Defaults for the options are specified in brackets.
1211
1212 Configuration:
1213   -h, --help              display this help and exit
1214       --help=short        display options specific to this package
1215       --help=recursive    display the short help of all the included packages
1216   -V, --version           display version information and exit
1217   -q, --quiet, --silent   do not print \`checking...' messages
1218       --cache-file=FILE   cache test results in FILE [disabled]
1219   -C, --config-cache      alias for \`--cache-file=config.cache'
1220   -n, --no-create         do not create output files
1221       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1222
1223 Installation directories:
1224   --prefix=PREFIX         install architecture-independent files in PREFIX
1225                           [$ac_default_prefix]
1226   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1227                           [PREFIX]
1228
1229 By default, \`make install' will install all the files in
1230 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1231 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1232 for instance \`--prefix=\$HOME'.
1233
1234 For better control, use the options below.

1236 Fine tuning of the installation directories:
1237   --bindir=DIR            user executables [EPREFIX/bin]

1282 Some influential environment variables:
1283   CC          C compiler command
1284   CFLAGS      C compiler flags
1285   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1286               nonstandard directory <lib dir>
1287   LIBS        libraries to pass to the linker, e.g. -l<library>
1288   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1289               you have headers in a nonstandard directory <include dir>
1290
1291 Use these variables to override the choices made by `configure' or to help
1292 it to find libraries and programs with nonstandard names/locations.
