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

 1276 Fine tuning of the installation directories:
 1277   --bindir=DIR            user executables [EPREFIX/bin]

 1307 Some influential environment variables:
 1308   CC          C compiler command
 1309   CFLAGS      C compiler flags
 1310   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1311               nonstandard directory <lib dir>
 1312   LIBS        libraries to pass to the linker, e.g. -l<library>
 1313   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1314               you have headers in a nonstandard directory <include dir>
 1315   CPP         C preprocessor
 1316 
 1317 Use these variables to override the choices made by `configure' or to help
 1318 it to find libraries and programs with nonstandard names/locations.
