1227 \`configure' configures this package to adapt to many kinds of systems.
1228
1229 Usage: $0 [OPTION]... [VAR=VALUE]...
1230
1231 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1232 VAR=VALUE.  See below for descriptions of some of the useful variables.
1233
1234 Defaults for the options are specified in brackets.
1235
1236 Configuration:
1237   -h, --help              display this help and exit
1238       --help=short        display options specific to this package
1239       --help=recursive    display the short help of all the included packages
1240   -V, --version           display version information and exit
1241   -q, --quiet, --silent   do not print \`checking ...' messages
1242       --cache-file=FILE   cache test results in FILE [disabled]
1243   -C, --config-cache      alias for \`--cache-file=config.cache'
1244   -n, --no-create         do not create output files
1245       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1246
1247 Installation directories:
1248   --prefix=PREFIX         install architecture-independent files in PREFIX
1249                           [$ac_default_prefix]
1250   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1251                           [PREFIX]
1252
1253 By default, \`make install' will install all the files in
1254 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1255 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1256 for instance \`--prefix=\$HOME'.
1257
1258 For better control, use the options below.

1260 Fine tuning of the installation directories:
1261   --bindir=DIR            user executables [EPREFIX/bin]

1290 Some influential environment variables:
1291   CC          C compiler command
1292   CFLAGS      C compiler flags
1293   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1294               nonstandard directory <lib dir>
1295   LIBS        libraries to pass to the linker, e.g. -l<library>
1296   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1297               you have headers in a nonstandard directory <include dir>
1298   CPP         C preprocessor
1299
1300 Use these variables to override the choices made by `configure' or to help
1301 it to find libraries and programs with nonstandard names/locations.
