1164 \`configure' configures mod_domaintree 1.5 to adapt to many kinds of systems.
1165
1166 Usage: $0 [OPTION]... [VAR=VALUE]...
1167
1168 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1169 VAR=VALUE.  See below for descriptions of some of the useful variables.
1170
1171 Defaults for the options are specified in brackets.
1172
1173 Configuration:
1174   -h, --help              display this help and exit
1175       --help=short        display options specific to this package
1176       --help=recursive    display the short help of all the included packages
1177   -V, --version           display version information and exit
1178   -q, --quiet, --silent   do not print \`checking...' messages
1179       --cache-file=FILE   cache test results in FILE [disabled]
1180   -C, --config-cache      alias for \`--cache-file=config.cache'
1181   -n, --no-create         do not create output files
1182       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1183
1184 Installation directories:
1185   --prefix=PREFIX         install architecture-independent files in PREFIX
1186                           [$ac_default_prefix]
1187   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1188                           [PREFIX]
1189
1190 By default, \`make install' will install all the files in
1191 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1192 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1193 for instance \`--prefix=\$HOME'.
1194
1195 For better control, use the options below.
1196
1197 Fine tuning of the installation directories:
1198   --bindir=DIR           user executables [EPREFIX/bin]
1199   --sbindir=DIR          system admin executables [EPREFIX/sbin]
1200   --libexecdir=DIR       program executables [EPREFIX/libexec]
1201   --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]

1203   --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
1204   --libdir=DIR           object code libraries [EPREFIX/lib]
1205   --includedir=DIR       C header files [PREFIX/include]
1206   --oldincludedir=DIR    C header files for non-gcc [/usr/include]

1229 Optional Packages:
1230   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1231   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1232   --with-apxs2            where the apxs2 tool is located
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   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1240               you have headers in a nonstandard directory <include dir>
1241   CPP         C preprocessor
1242
1243 Use these variables to override the choices made by `configure' or to help
1244 it to find libraries and programs with nonstandard names/locations.
