 1261 \`configure' configures this package to adapt to many kinds of systems.
 1262 
 1263 Usage: $0 [OPTION]... [VAR=VALUE]...
 1264 
 1265 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1266 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1267 
 1268 Defaults for the options are specified in brackets.
 1269 
 1270 Configuration:
 1271   -h, --help              display this help and exit
 1272       --help=short        display options specific to this package
 1273       --help=recursive    display the short help of all the included packages
 1274   -V, --version           display version information and exit
 1275   -q, --quiet, --silent   do not print \`checking ...' messages
 1276       --cache-file=FILE   cache test results in FILE [disabled]
 1277   -C, --config-cache      alias for \`--cache-file=config.cache'
 1278   -n, --no-create         do not create output files
 1279       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1280 
 1281 Installation directories:
 1282   --prefix=PREFIX         install architecture-independent files in PREFIX
 1283                           [$ac_default_prefix]
 1284   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1285                           [PREFIX]
 1286 
 1287 By default, \`make install' will install all the files in
 1288 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1289 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1290 for instance \`--prefix=\$HOME'.
 1291 
 1292 For better control, use the options below.
 1293 
 1294 Fine tuning of the installation directories:
 1295   --bindir=DIR            user executables [EPREFIX/bin]
 1296   --sbindir=DIR           system admin executables [EPREFIX/sbin]
 1297   --libexecdir=DIR        program executables [EPREFIX/libexec]
 1298   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
 1299   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]

 1325 Optional Features:
 1326   --disable-option-checking  ignore unrecognized --enable/--with options
 1327   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
 1328   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
 1329   --disable-openssl  disables openssl support
 1330   --disable-gnutls  disables gnutls support

 1332 Optional Packages:
 1333   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
 1334   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
 1335   --with-extra-libs=DIR   adds non standard library paths

 1337 Some influential environment variables:
 1338   CC          C compiler command
 1339   CFLAGS      C compiler flags
 1340   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1341               nonstandard directory <lib dir>
 1342   LIBS        libraries to pass to the linker, e.g. -l<library>
 1343   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1344               you have headers in a nonstandard directory <include dir>
 1345   CXX         C++ compiler command
 1346   CXXFLAGS    C++ compiler flags
 1347   CXXCPP      C++ preprocessor
 1348 
 1349 Use these variables to override the choices made by `configure' or to help
 1350 it to find libraries and programs with nonstandard names/locations.
