+Usage: $0 [options]
+
+When no options are specified, configure runs in interactive mode and you must
+specify any required values manually. If one or more options are specified,
+non-interactive configuration is started and any omitted values are defaulted.
+
+PATH OPTIONS
+
+ --system Automatically set up the installation paths
+ for system-wide installation.
+ --prefix=[dir] The root install directory. If this is set then
+ all subdirectories will be adjusted accordingly.
+ [$PWD/run]
+ --binary-dir=[dir] The location where the main server binary is
+ stored.
+ [$PWD/run/bin]
+ --config-dir=[dir] The location where the configuration files and
+ SSL certificates are stored.
+ [$PWD/run/conf]
+ --data-dir=[dir] The location where the data files, such as the
+ pid file, are stored.
+ [$PWD/run/data]
+ --log-dir=[dir] The location where the log files are stored.
+ [$PWD/run/logs]
+ --module-dir=[dir] The location where the loadable modules are
+ stored.
+ [$PWD/run/modules]
+ --build-dir=[dir] The location to store files in while building.
+
+
+EXTRA MODULE OPTIONS
+
+ --enable-extras=[extras] Enables a comma separated list of extra modules.
+ --disable-extras=[extras] Disables a comma separated list of extra modules.
+ --list-extras Shows the availability status of all extra
+ modules.
+
+MISC OPTIONS
+
+ --clean Remove the configuration cache file and start
+ the interactive configuration wizard.
+ --disable-interactive Disables the interactive configuration wizard.
+ --help Show this message and exit.
+ --uid=[name] Sets the user to run InspIRCd as.
+ --socketengine=[name] Sets the socket engine to be used. Possible
+ values are $SELIST.
+ --update Updates the build environment.
+
+
+FLAGS
+
+ CXX=[name] Sets the C++ compiler to use when building the
+ server. If not specified then the build system
+ will search for c++, g++, clang++ or icpc.
+
+If you have any problems with configuring InspIRCd then visit our IRC channel
+at irc.ChatSpike.net #InspIRCd.
