1173 \`configure' configures this package to adapt to many kinds of systems.
1174
1175 Usage: $0 [OPTION]... [VAR=VALUE]...
1176
1177 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1178 VAR=VALUE.  See below for descriptions of some of the useful variables.
1179
1180 Defaults for the options are specified in brackets.
1181
1182 Configuration:
1183   -h, --help              display this help and exit
1184       --help=short        display options specific to this package
1185       --help=recursive    display the short help of all the included packages
1186   -V, --version           display version information and exit
1187   -q, --quiet, --silent   do not print \`checking...' messages
1188       --cache-file=FILE   cache test results in FILE [disabled]
1189   -C, --config-cache      alias for \`--cache-file=config.cache'
1190   -n, --no-create         do not create output files
1191       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1192
1193 Installation directories:
1194   --prefix=PREFIX         install architecture-independent files in PREFIX
1195                           [$ac_default_prefix]
1196   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1197                           [PREFIX]
1198
1199 By default, \`make install' will install all the files in
1200 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1201 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1202 for instance \`--prefix=\$HOME'.
1203
1204 For better control, use the options below.
1205
1206 Fine tuning of the installation directories:
1207   --bindir=DIR            user executables [EPREFIX/bin]
1208   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1236 Some influential environment variables:
1237   CC          C compiler command
1238   CFLAGS      C compiler flags
1239   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1240               nonstandard directory <lib dir>
1241   LIBS        libraries to pass to the linker, e.g. -l<library>
1242   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1243               you have headers in a nonstandard directory <include dir>
1244
1245 Use these variables to override the choices made by `configure' or to help
1246 it to find libraries and programs with nonstandard names/locations.
