1137 \`configure' configures this package to adapt to many kinds of systems.
1138
1139 Usage: $0 [OPTION]... [VAR=VALUE]...
1140
1141 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1142 VAR=VALUE.  See below for descriptions of some of the useful variables.
1143
1144 Defaults for the options are specified in brackets.
1145
1146 Configuration:
1147   -h, --help              display this help and exit
1148       --help=short        display options specific to this package
1149       --help=recursive    display the short help of all the included packages
1150   -V, --version           display version information and exit
1151   -q, --quiet, --silent   do not print \`checking...' messages
1152       --cache-file=FILE   cache test results in FILE [disabled]
1153   -C, --config-cache      alias for \`--cache-file=config.cache'
1154   -n, --no-create         do not create output files
1155       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1156
1157 Installation directories:
1158   --prefix=PREFIX         install architecture-independent files in PREFIX
1159                           [$ac_default_prefix]
1160   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1161                           [PREFIX]
1162
1163 By default, \`make install' will install all the files in
1164 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1165 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1166 for instance \`--prefix=\$HOME'.
1167
1168 For better control, use the options below.
1169
1170 Fine tuning of the installation directories:
1171   --bindir=DIR           user executables [EPREFIX/bin]
1172   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1200 Some influential environment variables:
1201   CC          C compiler command
1202   CFLAGS      C compiler flags
1203   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1204               nonstandard directory <lib dir>
1205   LIBS        libraries to pass to the linker, e.g. -l<library>
1206   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1207               you have headers in a nonstandard directory <include dir>
1208
1209 Use these variables to override the choices made by `configure' or to help
1210 it to find libraries and programs with nonstandard names/locations.
