1165 \`configure' configures this package to adapt to many kinds of systems.
1166
1167 Usage: $0 [OPTION]... [VAR=VALUE]...
1168
1169 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1170 VAR=VALUE.  See below for descriptions of some of the useful variables.
1171
1172 Defaults for the options are specified in brackets.
1173
1174 Configuration:
1175   -h, --help              display this help and exit
1176       --help=short        display options specific to this package
1177       --help=recursive    display the short help of all the included packages
1178   -V, --version           display version information and exit
1179   -q, --quiet, --silent   do not print \`checking...' messages
1180       --cache-file=FILE   cache test results in FILE [disabled]
1181   -C, --config-cache      alias for \`--cache-file=config.cache'
1182   -n, --no-create         do not create output files
1183       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1184
1185 Installation directories:
1186   --prefix=PREFIX         install architecture-independent files in PREFIX
1187                           [$ac_default_prefix]
1188   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1189                           [PREFIX]
1190
1191 By default, \`make install' will install all the files in
1192 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1193 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1194 for instance \`--prefix=\$HOME'.
1195
1196 For better control, use the options below.
1197
1198 Fine tuning of the installation directories:
1199   --bindir=DIR            user executables [EPREFIX/bin]
1200   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1201   --libexecdir=DIR        program executables [EPREFIX/libexec]

1206   --includedir=DIR        C header files [PREFIX/include]

1228 Optional Packages:
1229   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1230   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1231   --with-pty-mode=mode    default mode for ptys
1232   --with-pty-group=group  default group for ptys
1233
1234 Some influential environment variables:
1235   CC          C compiler command
1236   CFLAGS      C compiler flags
1237   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1238               nonstandard directory <lib dir>
1239   LIBS        libraries to pass to the linker, e.g. -l<library>
1240   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1241               you have headers in a nonstandard directory <include dir>
1242   CPP         C preprocessor
1243
1244 Use these variables to override the choices made by `configure' or to help
1245 it to find libraries and programs with nonstandard names/locations.
