1180 \`configure' configures mod_domaintree 1.6 to adapt to many kinds of systems.
1181
1182 Usage: $0 [OPTION]... [VAR=VALUE]...
1183
1184 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1185 VAR=VALUE.  See below for descriptions of some of the useful variables.
1186
1187 Defaults for the options are specified in brackets.
1188
1189 Configuration:
1190   -h, --help              display this help and exit
1191       --help=short        display options specific to this package
1192       --help=recursive    display the short help of all the included packages
1193   -V, --version           display version information and exit
1194   -q, --quiet, --silent   do not print \`checking...' messages
1195       --cache-file=FILE   cache test results in FILE [disabled]
1196   -C, --config-cache      alias for \`--cache-file=config.cache'
1197   -n, --no-create         do not create output files
1198       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1199
1200 Installation directories:
1201   --prefix=PREFIX         install architecture-independent files in PREFIX
1202                           [$ac_default_prefix]
1203   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1204                           [PREFIX]
1205
1206 By default, \`make install' will install all the files in
1207 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1208 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1209 for instance \`--prefix=\$HOME'.
1210
1211 For better control, use the options below.
1212
1213 Fine tuning of the installation directories:
1214   --bindir=DIR           user executables [EPREFIX/bin]
1215   --sbindir=DIR          system admin executables [EPREFIX/sbin]
1216   --libexecdir=DIR       program executables [EPREFIX/libexec]
1217   --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]

1220   --libdir=DIR           object code libraries [EPREFIX/lib]
1221   --includedir=DIR       C header files [PREFIX/include]

1245 Optional Packages:

1248   --with-apxs2            where the apxs2 tool is located
1249
1250 Some influential environment variables:
1251   CC          C compiler command
1252   CFLAGS      C compiler flags
1253   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1254               nonstandard directory <lib dir>
1255   LIBS        libraries to pass to the linker, e.g. -l<library>
1256   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1257               you have headers in a nonstandard directory <include dir>
1258   CPP         C preprocessor
1259
1260 Use these variables to override the choices made by `configure' or to help
1261 it to find libraries and programs with nonstandard names/locations.
