1184 \`configure' configures this package to adapt to many kinds of systems.
1185
1186 Usage: $0 [OPTION]... [VAR=VALUE]...
1187
1188 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1189 VAR=VALUE.  See below for descriptions of some of the useful variables.
1190
1191 Defaults for the options are specified in brackets.
1192
1193 Configuration:
1194   -h, --help              display this help and exit
1195       --help=short        display options specific to this package
1196       --help=recursive    display the short help of all the included packages
1197   -V, --version           display version information and exit
1198   -q, --quiet, --silent   do not print \`checking ...' messages
1199       --cache-file=FILE   cache test results in FILE [disabled]
1200   -C, --config-cache      alias for \`--cache-file=config.cache'
1201   -n, --no-create         do not create output files
1202       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1203
1204 Installation directories:
1205   --prefix=PREFIX         install architecture-independent files in PREFIX
1206                           [$ac_default_prefix]
1207   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1208                           [PREFIX]
1209
1210 By default, \`make install' will install all the files in
1211 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1212 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1213 for instance \`--prefix=\$HOME'.
1214
1215 For better control, use the options below.
1216
1217 Fine tuning of the installation directories:
1218   --bindir=DIR            user executables [EPREFIX/bin]
1219   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1247 Some influential environment variables:
1248   CC          C compiler command
1249   CFLAGS      C compiler flags
1250   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1251               nonstandard directory <lib dir>
1252   LIBS        libraries to pass to the linker, e.g. -l<library>
1253   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1254               you have headers in a nonstandard directory <include dir>
1255
1256 Use these variables to override the choices made by `configure' or to help
1257 it to find libraries and programs with nonstandard names/locations.
