   1321 \`configure' configures LLVM 3.1svn to adapt to many kinds of systems.
   1322 
   1323 Usage: $0 [OPTION]... [VAR=VALUE]...
   1324 
   1325 To assign environment variables (e.g., CC, CFLAGS...), specify them as
   1326 VAR=VALUE.  See below for descriptions of some of the useful variables.
   1327 
   1328 Defaults for the options are specified in brackets.
   1329 
   1330 Configuration:
   1331   -h, --help              display this help and exit
   1332       --help=short        display options specific to this package
   1333       --help=recursive    display the short help of all the included packages
   1334   -V, --version           display version information and exit
   1335   -q, --quiet, --silent   do not print \`checking...' messages
   1336       --cache-file=FILE   cache test results in FILE [disabled]
   1337   -C, --config-cache      alias for \`--cache-file=config.cache'
   1338   -n, --no-create         do not create output files
   1339       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
   1340 
   1341 Installation directories:
   1342   --prefix=PREFIX         install architecture-independent files in PREFIX
   1343 			  [$ac_default_prefix]
   1344   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
   1345 			  [PREFIX]
   1346 
   1347 By default, \`make install' will install all the files in
   1348 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
   1349 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
   1350 for instance \`--prefix=\$HOME'.
   1351 
   1352 For better control, use the options below.

   1355   --bindir=DIR           user executables [EPREFIX/bin]
